Hello,
I'll try to explain (in english !) my problem about pseudorandom number =
generator (PRNG).
I'm looking for a PRNG for seeding a cryptographically secure PRNG. So, =
to test several PRNG, I wrote a program that seems not present in any =
test suite:
1.. utilizing the PRNG to test, my program generate and store =
1,000,000 of different keys each 5 bytes long;
2.. sort the keys;
3.. generate others 100,000,000 keys (5 bytes long) and verify how =
many keys are the same to these generated at step 1.
The program, obviously, verify that a particular sequence of bits is not =
repeated often (my free program in Borland C++ Builder v1.0 is available =
on request).
These are the results:
test n.

Mother: George Marsaglia's The mother of all random number generators =
producing uniformly distributed pseudo random 32 bit values with period =
about 2^250.
=20
CryptGenRandom: Windows 95/98 CryptoAPI 1.0 (criptographically secure =
software PRNG).
=20
URAND: Porting of a FORTRAN generators producing uniformly distributed =
pseudorandom 32 bit values.
=20
random: standard c library.
For example with Mother, in 100,000,000 keys, 92 keys are the same as =
these generated in the fisrt 1,000,000 keys in the first sequence (n=B0 =
1), 99 keys in the second seuence, and so on.
With my test, the best generator is "URAND" (few repetitions) while the =
worst is "random" (many keys are the same).
Other generators (Mersenne Twister, ranmar, etc.) are about the same as =
Mother (or a little bit better).
The differences in the table above are not detected by any statistical =
test used in my program (FIPS PUB 140-2, Diehard, Maurer's universal =
statistical test and others).
Can anybody say me if my test is right? Why the statistical tests =
doesn't detect these differences?
Tank you very much.
Ciao
Cristiano

To be too anxious of every potential risks is useless and
doesn't help. But to be blind of potential risks simply
because some big names 'guarantee' that things are o.k.
is naive. In fact, one gambles in all non-trivial
circumstances in life, because the outcomes are hardly
ever known for sure. Whether one can or needs or is
reasonable or cares to do something additional to reduce
the potential risks in ANY issue depends very much on
the environment one is in and of course also on one's
(subjective) evaluations. It is important to realize,
though, that one is alone responsible for one's decisions.
(The experts who have given advices don't carry
responsibilities for you in case things happen to come
out other than in ways prophesied by them.)

For security issues the German newsgroup de.comp.security
is quite active. You would have a better chance of getting
an answer to your question, if you post to that group.

On the contrary. Advanced statements at the forefront of
research are under debate. As such they are both false and
true, simultaneously, in the minds of well-informed experts.
In the page http://www.hit.fi/~lounesto/counterexamples.htm,
I falsify theorems by counterexamples, which satisfy all the
assumptions of the theorems, without the conclusions being
valid. Those theorems are at a transition from true to false.

You've been politely asked several times now for details of what
you're proposing, but as with this message, you seem to evade the
question and come back with ad-hominems.
So, for the last time, what are the details of the math you are
proposing (note: I'm entirely neutral on the math here -- I'm just
watching from the sidelines).

Your hypocritical ad-hominem attack is noted.

Is it right that each call of the generators gives you
a 5*8=40 bit integer? What are the moduli of the
generators? You examined sequences that are repeated.
Did you examine repetition of sequences of certain
given fixed length (what is that?) in the concatenation
of the said integers (resulting in a big bit sequence)
or what did you do? Without these informations it seems
difficult to understand the meaning of your table.
