One time pads

2002-10-16 Thread Sarad AV

hi,

An extract frm this months cryptogram goes as below.


On the other hand, if you ever find a product that
actually uses a one-time pad, it is almost certainly
unusable and/or insecure.
So, let me summarize.  One-time pads are useless for
all but very specialized applications, primarily
historical and non-computer.  And almost any system
that uses a one-time pad is insecure.  It will claim 
to use a one-time pad, but actually use a two-time pad
(oops).  Or it will claims to use a one-time pad, but
actually use a steam cipher.  Or it will use a
one-time pad, but won't deal with message
re-snchronization and re-transmission attacks.  Or it
will ignore 
message authentication, and be susceptible to
bit-flipping attacks and 
the like.  Or it will fall prey to keystream reuse
attacks.  Etc., 
etc., etc.
-

Though it has a large key length greater than or equal
to the plain text,why would it be insecure if we can
use a good pseudo random number generators,store the
bits produced on a taper proof medium.

how about this way

P=Plain text 
C=Cipher text 
R=Pseudo random bits(the pad)

To transmit a secret frm point A to Point B 

Choose ur agent-Send cipher text(C) to B. 
If( Cipher text C is intercepted,do not send R.) 

without R, C cannot be decrypted 

Else(If C is securely transmitted to point B,choose an
agent and send R to point B) 

If R is intercepted the secret remains safe,since they
donot have C. 
If initially C was intercepted ,R is not send,another
pad is chosen. 

It is assumed that the agent is trust worthy.Also the
agent has to send receipt 
for the safe arrival of C at point B before R is
transmitted. 
It is also assumed that cryptographical secure pseudo
random numbers are use. 


Cryptography does not address the problem of dishonest
users-does it?

The difficulty for attaining highest security is more.

why do we always have to rely on the internet for
sending the pad?If it is physically carried to the
receiver we can say for sure if P or R is intercepted.


can some one answer the issues involved that one time
pads is not a good choice.
Thank you

Independence and redundncy Re: XORing bits to eliminate skew

Two events E1 and E2 are said to be independent,if
P(E1(intersection)E2)=P(E1).P(E2)

As in the above case we assume that the bits under xor
are independent.

if the inputs are frm different sources then we
consider them independent.

what about the following case.

i open any two text files in binary mode and xor 1 st
bit of file 1 with file 2,2 nd bit with 2 nd bit with
second bit and so on.

The rate of english varies between 1.0 bit /letter &
1.5 bit/letter for large values of N.

absolute rate of english is R=log(26)base 2=4.7
bits/letter

There is lot of redundancy in the language,0.6 to 0.85
percent redundancy.

Since in ASCII we use 8 bits to represent english
alphabets,the redundancy is 8-1.3=6.7 bits/charecter
of redundancy.

Since in both files opened,english charecters are
represented in the same set of ASCII charecters.

there is redundancy in both the files.
Does that mean that such bits we xor are not
independent?

XORing bits to eliminate skew

2002-10-17 Thread Sarad AV
hi,

In the book on Applied Cryptography by Bruce
Schenier,it goes like this...


let p(0) be the probability of occurance of 0
and p(1) be the probability od occurance of one.

let 
p(0)=0.5+e
p(1)=0.5-e

where e is the bias of the bit towards 0 or 1
ideally e=0 & P(0)=P(1)=0.5(no bias condition,ideal)

XORing 2 bits together yeilds

let ^ denote-to the power of
p(0)=(0.5+e)^2+(0.5-e)^2=0.5+2*(e^2)

Xoring 4 bits together we get,

P(0)=0.5+((8*(e^4))

How are these results obtained?

It is my understanding that the result is obtained
because

a=p(0)=0.5+e
b=p(1)=0.5-e

If ~ denotes negation,~a means negation of a.
Xor of 2 bits a & b is  y=~a.b+a.~b


P(0)=(0.5-e)(0.5-e) + (0.5+e)(0.5+e)

P(0)=(0.5-e)^2 + (0.5+e)^2
P(0)=0.5+(2*(e^2))

and similarly by xoring 4 bits we get

P(0)=0.5+((8*(e^4))

This is how I understand this result is obtained.

My teacher how ever asked me,how I was possible to do
such an arithmetic when xor is defined only for binary
digits (0 and 1).

He wanted to know how I was able to do XOR on P(0) and
P(1) when xor is defined only on binary digits.




I am stumped now and may be i am making a mistake some
where.

how was the actual result  shown below obtained?

XORing 2 bits together 

p(0)=(0.5+e)^2+(0.5-e)^2=0.5+2*(e^2)

Xoring 4 bits together ,

P(0)=0.5+((8*(e^4))


Pls help.

Doubt on Hill Cipher

hi,

I was going through Hill Ciphers at

the very last line on the page regarding finding the

A comma is placed to prevent space formating.
k*k(inverse)=

131,  78  
182, 105 //multiplication leads to 105

There is a small typo there A(2,2) is 105 and not 104.

Regarding find k(inverse) it is unclear how
they get
7,  21
22, 3

since

I was expecting k(inverse) to be
7,-5 
-4,3

which is the actual key here?

both seem to be right,since both holds

Re: Psuedo-Private Key -Methodology

2002-11-21 Thread Sarad AV
hi,

The methodology is very simple again.

'A'  uses a very strong crytographic algorithm which
would be forced out by rubber horse cryptanalysis
Now if Aice could give another key k` such that the 
cipher text (c) decrypts to another dummy plain
text(D) 
the secret police gets to read 
the dummy plain text(D) using the surrendered key k` 
without compramising the real plain text(P). 

goes like this. 
p=plain text 
c=cipher text 
D=dummy plain text 
k=oiginal key 
k`=dummy key. 

Now A encrypt using a good asymmetric key 
algorithm. 
Now A has cipher text C. 
Now A takes her Dummy plain text (D) and she, 
C (xor) D=k` 
Now to the secret police she can surrender k`. 
The secret police decrypts dummy plain text D as 
D=c(xor)k` 
She can now say that she used k` as one time pads to 
encrypt C. 

There is no way to prove that k` is not a valid key
unless 
they ever get hold of k. 

hOW ever as what is said,it doesn't look like it will
work.

DigiSecret currently does not use assymmetric

the introduction of this technique will mean that the
secret police 
will also know about this fact, so the person's
harrowing experience with the

Isn't that the reason we call it 'undecidable',put it
in an undeciable list which is the truth.
We can actually write these symbols down,it will be
true for some and false for some

eg: If we say-For a context free grammar G, L(G) is
ambigious.This is true for some G and false for G,If
we ask a turing machine to solve this question,it
can't because there is no algorithm to determine the
statement is true or false. A function is turing
computable only if for every element in the domain,the
function's value can be computed with a Turing
machine.
The domain is important,for sime G we get True and
some G we get false.By the defenition of turing
complenetess,since we cannot show it is true or false
for every element in the domain,it is not turing
computable and hence undecidable.We can write down the
symbols but it does n't mean any thing.

Mathametics is incomplete,other wise we would have

observation and experience we know that we don't know

to be incomplete. Showing that a set of mathametics as

Don't encrypt,post it by snail mail.I remember reading
this in pgp's help document.
It addresses why we glue over our envelope and seal
it.It ofcourse is concealing(for the govt) and privacy
(for the user).The govt. never asks letters not to be
glued and sealed because of the vast majority of
people using it.
But at the slightest at the use of encryption will

This issue can only be fully solved when the vast

Re: Many Worlds Version of Fermi Paradox

2002-12-31 Thread Sarad AV
hi,

A few queries.

Does a paradox ever help in understanding any thing?
We define a paradox  on a base of rules we want to
prove.

Ok,let me pick an example.



We make a paradox over a statement.

This i found on the net

The following is an implication that the Oracle does
not exist. 
1.Someone introduces Gödel to a UTM, a machine that is
supposed to be a Universal Truth Machine, capable of
correctly answering any question at all. 
2.Gödel asks for the program and the circuit design of
the UTM. The program may be complicated, but it can
only be finitely long. Call the program P(UTM) for
Program of the Universal Truth Machine. 
3: Gödel writes out the following sentence: "The
machine constructed on the basis of the program P(UTM)
will never say that this sentence is true." Call this
sentence G. G is equivalent to: "UTM will never say G
is true." 
4:Now Gödel asks UTM whether G is true or not. 
5:If UTM says G is true, then "UTM will never say G is
true" is false. If "UTM will never say G is true" is
false, then G is false (since G = "UTM will never say
G is true"). So if UTM says G is true, then G is in
fact false, and UTM has made a false statement. So UTM
will never say that G is true, since UTM makes only
true statements. 
6:We have established that UTM will never say G is
true. So "UTM will never say G is true" is in fact a
true statement. So G is true (since G = "UTM will
never say G is true"). 
"I know a truth that UTM can never utter," Gödel says.
"I know that G is true. UTM is not truly universal." 


Firstly if you see the following statements are
consistent for both positive and negative logic.
The question is it in a formal system,since we don't
have paradoexes in a formal system.Any formal system
is consistent, i.e. there is no proposition that can
be proved true by one sequence of steps and false by
another, equally valid argument.

Secondly,how do we define the oracle.If I say an
oracle is one who knows every thing about every thing.

You may not agree-you may come with your own 
defenition of an oracle,some one else will come with a
different defenition of the oracle.

With my defenition of the oracle-the above set of
statements showing that the oracle does not exist is
true.If you define oracle in a different manner-the
statements shown above may not lead to the conclusion
that "Oracle does not exist".

Its how I define the oracle and how I put the
statements which give me the amswer I want.Anybody can
do that and come with a consistent system.

We have to see that if all over defenitions and
statements fall in a formal system,which we *donot*.We
know that the oracle problem is undecidable,yet the
above statements showed that the oracle doesnot
exist-"in the domain in which the oracle was defined
and statements over it."
Same is for all paradoxes-they are only consistant in
the small domain they are defined-other wise they are
undecidable in a formal system over a larger domain.So
paradoxes doesn't say any thing.when we assign a sense
to a paradox,it stops becoming a paradox but is only
true for its set of defenitions and statements. 

Its also worth noting  paradoxes try to make their
point by the method of falsification rather than proof
by contradiction.

What about just making your own key pair and not
putting it on any key server.The govt will have enough
reason that the keys were communicated by other means
than putting it on a key server and they will still
have be interested in it,making key pairs is not a
hard task,if spammers have utilities like pgp,even
spammers can do that.So spammers don't have to worry
*more* of getting traced.It should give the govt.
enough work. :)

it is better that every one start encrypting their
mail-the idea would be then half of the world policing
will have to watch the other half of the world which
are civilians-which is not very feasible,thats what I
think.

An axiom is an improvable statement which is accepted
as true. A Formula is a finite set of algebraic
symbols expressing a mathematical rule. Proofs, from
the formal standpoint, are a finite series of formulae
(with certain specifiable characteristics).Hence any
proof has a deterministic and well defined sequence of
steps. 
So since we are 'proving'  that the oracle does n't
exist-its program has finite.

This is true by the way I define a proof.
You are right in ur context and I am right in my
context.So both of us are right?yes,based on the
*sense* of what  we mean by a proof.

Any formal system is consistent, i.e. there is no
proposition that can be proved true by one sequence of
steps and false by another, equally valid argument-by
defenition and property of the system (I call the
above defenition a formal system,others might not) we
cant have a paradox in a formal system.

we cannot as reasoned above.If we have-we don't call
it a formal system-it can how ever still be a
*consistent* system

 > * note that Godel uses 'consistent' where we use

consistent and complete are not the same.
Complete means-true for all the possible values of all
the domains.
Consistent means-true for some values of domains and
its consistency is uphelid in the domain but  not 
outside.
its the *domain*-which we are concerned about.

A Formula is a finite set of algebraic symbols
expressing a mathematical rule---its a set of symbols
and certainly we cannot prove a set of symbols.Yes
thats true.

it says proposition formula which states c is
consistent is not provable.

Yes-thats what godels second incompleteness theorom
says.The following statement is true but not provable.

by the way can you point me to a undecidable problem
in a formal system?

Yes,ok-i understand what you mean.

As you already see-what you say is correct for your
definition of proof and axiom.
I never said you are wrong-I only said that I am right
 according to my set of defenitions and statements in
the context I mean.You are right according to your
definitions and statements.


you said

Wrong, there is -nothing- that says the program must
have finite length
-or- halt.

Acoording to my definition of proof,I am right and
according to your definition you are right.But you
said 'Wrong', there is nothing...

Thats the only thing I disagree with.

If we accept that both arguments are right-every thing
is clear and there is no more confusion.

This discussion never ends other wise because-

for a given definition -we interpret it in different
ways.
Some times we don't agree on the sense of the
definition.

Its how acccording to the definitions and statements
we make,the result we come up with.
 
Thats where-I am not convinced with paradoxes and the
fermi paradox either.

I agree with the further discussion in this mail-Thats
another way of seeing it.

I think-i get your point now-I was comming to the same
conclusion.We need a model which works rather than
comming up with a model which does not work.If they
later disagree with observations we can update our
model.Thank you for this discussion-it is very
sensible.


There is still one thing left-how useful or how close

Liars Paradox

2003-01-03 Thread Sarad AV
hi,



with reference to

http://www.utm.edu/research/iep/p/par-liar.htm

it says


The Liar Paradox is an argument that arrives at a
contradiction by reasoning about a Liar Sentence. The
most familiar Liar Sentence is the following
self-referential sentence:

(1) This sentence is false.
Experts in the field of philosophical logic have never
agreed on the way out of the trouble despite 2,300
years of attention. Here is the trouble--a sketch of
the Liar Argument that reveals the contradiction:

If (1) is true, then (1) is false. On the other hand,
if (1) is false, then it is true to say (1) is false;
but, because the Liar Sentence is saying precisely
that (namely that it is false), (1) is true. So (1) is
true if and only if it is false. Since (1) is one or
the other, it is both.

As it says-they are self referecial statements.What do
we learn from the liars paradox?

We arrive at a senseless result-doesn't all other
paradoxes do that-with the difference that they pick
only either true or false-which "they so strongly
beleive in" and come with the result they want?IS n't
that all paradoxes are trying to do?

what about this
http://xray.sai.msu.ru/~lipunov/text/ashkl/node3.html

http://www.transhumanism.ndtilda.co.uk/Fermi.htm
it says

There has been much speculation around Fermi's famous
question: "Where are they? Why haven't we seen any
traces of intelligent extraterrestrial life?". One way
in which this question has been answered (Brin 1983)
is that we have not seen any traces of intelligent
extraterrestrial life because there is no
extraterrestrial life because intelligent
extraterrestrial life tend to self-destruct soon after
it reaches the stage where it can engage in cosmic
colonization and communication. This is the same
conclusion as that of the Doomsday argument (i.e.: we
are likely to perish soon), but arrived at trough a
wholly different line of argument.


So does the fermi paradox mean that there are no extra
terrestrials.Can't we throw away this paradox like
every other paradox?

Look at this view point.

I say that "The earth is flat and round".

now lets attach a meaning to it that we make a sense
out of it.

The earth is flat when I observe from the earth.
The earth is round when I observe it from space.

It depends on the frame of reference.

When you are on earth you agree that  the earth is
flat.
when you are in space you agree that the earth is
round.

how ever you don't agree to me saying that both are
right.

As you see they are not equivalent either because
their *domains*-which is the frame of reference are
different.

thats my view point.

It will be a proposition then-won't be an axiom.If we
find that the two axioms are inconsistent with each
other-its time we update our axioms and they will
become propositions and no more axioms.The theory as
such doesn't collapse.

hi,


I guess inspite of all these questions-I will wait
till I get to see a real one.But how will I know if it
was a real  alien?

what if we are being tricked-If I could go back in
time along with  a projector that projects a
holographic image of an alien and trick our ancestors 
to beleive that they had seen an alien,how less
probable are we being tricked of the same.I think
thats one more question you can add to that list.


the argument is fine but there are as you say too many
unknowns and there is no meaning on operating on them
as if they were constant,we want models for things we
observe and not what we speculate-so may be there is
no point in speculating since we only end up with same
questions and our understanding gets no better than it
was.

Re: Desert Spam(The war)

2003-01-18 Thread Sarad AV
hi,


Does n't that also mean that the US will have to time
well the ending of the war or the fall of iraq(If iraq
is to fall-that we will have to wait and see).

Usually we have oil reserves which can last three
months from the start of the war.How ever then the US
will not be able to sell it-until the reserves of
other countries dry out.

That would mean that it cannot let iraq fall at an
early stage of the war.No body will buy the oil from
US then and US will not be able to cover up the cost
of the war or may be even make profit of it.

So if US tries  blitzkrieg-iraq may fall in less than
100 days but they can't afford that to happen.They
would have to wait till the other countries oil
reserved dry out-sell the oil-make the money and then
invade iraq.

It also would mean that there can be no more countries
around iraq drawn fully into the war for US.

If Iran or Israel would attack iraq then the US oil
equation will not work.There are also enough sects in
and around iraq who will fight their way into iraq
once they find iraq is going to fall at any point
during the war.So US will want iraq be able to defend
its territories till it can sell the oil.Once that is
done-it can have its free run on iraq. 
It also might mean a long campaign the arieal route
-missiles and bombs from planes.The ground troops will
be only pressed only when iraq would be ready to be
fell.
US seems to run a very big gamble for very big
money.Will have to  see how well it works and what
surprises iraq can come up with.

Its always better to choose an algorithm because it
has *known* properties-such as period of the
generator,whether it passes the die hard test and so
on.Once we know it  by using a one way function we can
say with some confidence that the generated output has
good random properties.

Using the output to seed MD5 for the next block

Regarding linear recurrences.

2003-03-27 Thread Sarad AV
hi,

Need help on understanding the following marix
multiplication.

let _ denote subscript.
w=32 bits(0 to 31)

let X be a 32 bit vector
X={X_(w -1),x_(w-2),..x_0}


A=
|1 0 . .|
|0 .|  
|.   .  | 
|. .|  
|a_(w-1) a_(w-2)a_0 |


i.e A is an identity matrix w ith last row entries
a_(w-1) a_(w-2)a_0  which is again a 32 bit vector

We multiply 1*w matrix X with w*w matrix to get a 1*w
matrix as follows

X*A=[X_(w-1)+ X_0*a_*(w-1) , X_(w-2)+
X_(w-2)*a_(w-2),..., X_1+ X_1*a_1 ,
X_0*a_0];


it is said- X*A can be calculated using bit wise
operations as follows

X*A
=
XOR {0 if the least significant bit of
y=0;(multiplying A)
XOR (a if the least significant bit of
y=1;(multiplying A) 



how does this hold?

thank you.

hi,

All this happening on the worlds greatest demcoracy.
may be you read this news.

http://news.yahoo.com/fc?tmpl=fc&cid=34&in=tech&cat=hackers_and_crackers

Unofficial reports are that 500 iraqi's died 2 days
ago and day  before yesterday another 1000 died.This
is the word comming from Saudi-from friends.Dunno if
the casualities are iraqi civilains or the army.
US bombers are any way doing cluster bombing in
civilian areas.They are finding it hard to hit
armoured vehicles since they are well spread out in
distinct patterns.US has told iraq to treat US
soldiers as pow's and follow the geneva
convention.they showed images of 3 US pow's,one women
and 2 men-one of them were bandaged on their
head.These had appeared a few hours after US made a
press conference saying that they had taken 3000
iraqi's pow's and there were no US pow's.

Iraq replied by asking them to follow the geneva
convention and not to do cluster bombing in civilan
areas.

In any case US military pow's are going to have a hard
time and since U.S didnot give pow status to
*suspected* Al-Queda/taliban militants captured in
afghan war-no body is going to put pressure on iraq
either.

RE: U.S. Drops 'E-Bomb' On Iraqi TV

2003-03-29 Thread Sarad AV
hi,

Well it is more than obvious that the US troops are
avoiding civilians-the reason is different though.
The iraqi republican troops are not fighting in
uniform-ther are fighting in kutra-traditional muslim
dress.You don't know who is a civilain and who is an
iraqi army personal-the US army is trying to reach
baghdad with out getting into trouble.They have had
enough.Being in  a desert storm for one night is
enough to keep one in bed for a week.The US army is
already suffering from fatigue,the troops called on
for air support to hit an iraqi  armoured vehicle but
turned out to be bushes and desert shrubs.
The US troops were fighting each other-when iraqi
guerilla's fired on both sides and the US troops ended
up shooting each other.
The US soldiers are finding to figure out who are US
soldiers themselves at first glance-US army dresses
were found in Nadarayiah and today one suicide bomber
blew up 5 US soldiers.
They claim that this war is not what they saw in their
war game.


Any way one thing is clear-superior missile,aircraft
or other electronic substitutes cannot win a war.The
US would need more ground troops in iraq and US is
always one step back in putting ground troops fearing
casualities.So may be if a country has 500,000
soldiers even US might not win a war against them.

Except for 'smart bombs' which has an accuracy 95% and
the only bombings shown on TV-what about the rest.Even
the patriot missles has a success hit rate of 1 out of
3.Is true that iraqi's are putting anti air craft and
other light arms over civilian buildings-that should
be the reason they got hit. 
How ever I wonder if the report of an Apache
helicopter being shot down by a farmer with his
rifle-the chopper was certainly downed but I find it
hard to beleive that a bullet brought it down. 

The images shown at the begining of the war showing
iraqi soldiers surrending and walking up with their
hands behind their head might have cost US dear again.
Iraqi tv then showed a iraqi general with a large
rifle in his hand saying to iraqi tv-what do you think
when I have this (rifle) in my  hand,i wont die
without killing two of them.
After the war started  around 3 civilians have
joined the war as small unorganised groups.

If the war drags to mid april the US troops wont stand
the intense heat,i mean its going to hard for them.

More than propaganda-they pubicly claimed that nukes
are not made to be kept on the shelves.Any way there
is nothing much any body can do about it-be it india
or pak or US or Russia.India also has a self imposed
moretarium of no first use of nukes.
US conducted nearly a thousand nuclear tests over the

testing nukes.Every one does have a propaganda whether

hi,

Why are  the suicide bombers after US troops-its the
hate.It does work .Yesterday at najaf(iraq)-a family
of 8 women and atleast 2 children were killed by
allied troops.They claimed that the vehicle sped
towards an allied check post.So they fired warning
shots to *stop* the vehicle.
When it didn't stop-they opened fire at the passenger
compartment.Then they figured out they were a
family(iraqi civilains fleeing).One of the women was
still hodling the bodies of 2 children and she refused
to step out.The allied troops maintained that they had
the right defend themself at check posts and any
where.
They said that they would have to be careful of
suicide bombers.

When a vehicle tries to flee at high speed-how can
they be suicide bombers.A suicide bomber will go
slow,stop at the check post and see that he can kill
as many people as possible.
where was the logic in killing these civilians-and
this report was confirmed by allied soldiers.

For those who read this-the hate is growing,all over

The operation * is associative iff (a*b)*c=a*(b*c) for

Re: Q on associative binary operation

2003-08-29 Thread Sarad AV
hi,

Let ~ represents a relation.

If a~b and b~a,then

a~a (by transitivity)
is an incorrect argument.

By definition of transitivity, if a~b and b~c implies
that a~c.

I was asking on the same lines if (a*d)*d=a*(d*d)=d.

By definition associativity is defined on a,b,c
element of set S and not two elements of the set.

x*y (ie, left*top) can be followed.

hi,

Thank you-one more question.
Will the information obtained from the 2^32 tests have
a zero compression rate? 
If one of the occurance should yield all heads and one
occurance yields all tails-there appears to be scope
for compression.

If the output is random,then it will have no
mathametical structure,so I shouldn't be able to
compress it at all.

Re: paradoxes of randomness

2003-08-17 Thread Sarad AV
hi,

Okay- I need 5 bits to represent 32 coins.I count as
coin 0,coin 1,... coin 31.
If it is a perfectly random fair coin throwing
experiment,then 50 percent of them will be heads.

So I know that 16 of them will be heads.

What we do is i simply place all the 32 coins on the
table in a row or column.
I look at the first coin and determine if it is a head
or a tail. I repeat the same proccess till i count 16
heads. If I count 15 heads at coin 31, then I cant
reduce the entropy. How ever, if i count 16 heads at
coin 30,then I dont have to check that coin 31,I
already know its a tail,so I have less than 5 bits of
entropy.

So if it is a perfectly random experiment,I wouldn't
get 16 heads before i look at coin 31,which is the
last coin and thats what you said-isn't it?

So how did chaitin get to compress the information
from k instances of the turing machine in

http://www.cs.umaine.edu/~chaitin/summer.html 

under the sub-section redundant?

he says-
"Is this K bits of mathematical information? K
instances of the halting problem will give us K bits
of Turing's number. Are these K bits independent
pieces of information? Well, the answer is no, they
never are. Why not? Because you don't really need to
know K yes/no answers, it's not really K full bits of
information. There's a lot less information. It can be
compressed. Why? "




If the input programs are truely random-there is no
redundancy and thats a contradiction to the claim in
the paper.

Thanks.

If we are to convert a k-bit integer n to a base b
number,it takes us O(log n) if the base b is a power
of 2 is still a correct statement.

Say if we are to multiply a k-bit integer n with the
same k-bit integer n,  i.e multiplying 
integer n with k-bits by itself.


The multiplication takes atmost k^2 bit operations.

eg.

n=5=101 base 2.

i.e the multiplication takes atmost 3^2=9 bit
operations.
Thus multiplication of O(k^2) for a constant c and
n>=no.

All logarithms are to the base 2.

Since k=[log n]+1

k^2=([log n]+1)^2
in our example

= ([log 5]+1)^2

=3^3=9 operations.

it is correct to write O(log n)=O(k), as n or k are
the inputs to an algorithm whose time complexity is to
be determined. O(log n)=O(k)is the time the algorithm
takes for processing the input which are essenctially
the same.

yes,I was asking if there is an algorithm in 
O(k)=O(log n) to convert a k-bit integer n to
arbitrary base. I only know to do it in O(k^2).

They rely on other methods to detect and nullify
terror threats. Even if every one started using

Re: Deniable data storage

2003-11-06 Thread Sarad AV
hi,

Keep

K =Original Key
P =Original Plain Text
C =Original cipher text
D=Dummy plain text
C'=Dummy cipher text
K'=Dummy key

use a symmetric key encryption algorithm with a secret
key 'k' over plain text 'P' to obtain cipher text 'C'

Then we find

k'= C (xor) D

Preferably D is atleast as long as C.

Now we can claim we used k' as one time pad to
encrypt.
 
When the police decrypts they obtain
D= C (xor) k', the dummy plain text.

This is not an efficient algorithm but even if you did
have one, this is not a very good idea because the
secret police will first get the dummy key and when
they see there is nothing of significance in the plain
text, they will beat the original key out of us and I
dont suppose any democracy in the world prevents this
from happening :-)

And 'net social issues were not widely discussed; now

Lets be a little fair here, just copying and just
chatting during exams are malpractices, the students
have much political support and relegious support in
these places.
As for openly consulting books durin exam,most of the
universities don't conduct open book exams,except may
be at the iit's.Its a malpractice,elsewhere.

The university sends special squads appointed by the
university itself to check exam malpractices, how ever
if the students counter the squad with sickles and
knifes and swords-it becomes a common practice that
the invigilators get armed police protection. So,in a
riot when the students are out to kill,very little can
be done to protect themselves and people sadly,get
killed.

Computer scientists are very few. Most engineering

The math education system from schools to colleges is

strike and where it will strike. So,spending billions
of dollars for a mar mission is certainly not a
problem.you never know when it might come in handy :-)
There are bigger issues to be solved,why go after
this.

cloak their secrets? (fwd from dave@farber.net)

2004-02-04 Thread Sarad AV

if  terrorists used compression instead of
cryptography,it is not possible to determine that they
are terrorists in the first place. If some one knows
that,the given person is a terrorist,you can bust him
whether or not he uses cryptography.Just because 
terrorist uses cryptograhy, doesn't allow others to
identify him as a terrorist and if you cant identify a
terrorist,it is immaterial that he uses crypto or not.

This never should be the reason for govt. to moderate
cryotography in the future.

Very true :)

Its election year in U.S. Once they are over,they
would pass another bill that would again allow
outsourcing. 

Who wouldn't want to get their works at cheaper rates.
Now a days,in Indian call centers,people with Mother
Tongue Influence are not taken for the job.They are
also asked to keep their normal accent and not to
mimick the british or american way of speech,most of
them here try the british accent.

May be in one or two years,speech should appear
neutral and no signs of culture would be
detected.Except for the Slangs,communication should be
clear.

inverse finding

hi,


if gcd(a,m)=1,
for a*a inverse==1 mod m
is it better to find
a invese=a^(m-2) mod m   by binary exponentiation
modulo m  or is it more time efficient by extended
euclids algorithm for large 'm'?

thanks.

Re: Diffie-Hellman question

2004-05-18 Thread Sarad AV
hi,

In Diffie Hellman key exchange we choose a large prime
in Fp. The prime is publicly known,so is g,preferably
a generator in Fp*.

The reason that you might need to change the prime
frequently is only if you donot choose g(element of)Fp
to be a generator in Fp or the prime field be too
small.
If the attacker knows the prime factorization of p-1,
where p-1=q_1*q_2*...*q_n,he can compute which of
 g^((p-1)/q_i)== 1 mod p and determine the order of g.
If it has a lower order, the attack is easier.

If you choose g of maximum order in Fp, then you will
have maximum security.

> physical retrieval of the DH prime (and the rest of
> the certificate) allow
> him to decode the captured log?

The diffie-hellman key exchange works under the
assumption that knowing only g^a and g^b, it is
computationaly infeasible for the attacker to
calculate g^(ab) and breaking it is conjenctured to be
as hard as the discrete log problem.
