This fairly screams for an empirical validation, doesn't it, though?
I think the problem here is one of successive approximations --
measure twice, cut once, and all that. In particular, I don't
know of any experiment or study that has ever suggested that
the entropy of "free" English text is as low as 1 bit/character;
more typical bounds are on the order of 1.5-1.8 (or even 2.0) bits/char.
Of course, if you want to round (conservatively) to 1 bit/char,
you're betting on the side of caution; given that improved
models are more likely to *decrease* the measured entropy than
to increase it, that's probably the direction one wants to go.
*BUT*....

How much are you willing to throw away? We're entering the realm of
engineering here -- what's the bang/buck you want? But you can see
that just in rounding down from 1.5 to 1.0 bits/char, you're already
"throwing away" 1/3 of the entropy in the sample in your back of
the envelope calculations.

Yes, like in a radioactive TRNG. But as you point out, the TRNG is
biased slightly no matter how careful you are.
In contrast the numbers generated by a quantum computer are pure
random numbers that don't suffer from experimental bias (or
correlation).

You know that, and I know that - but you would be surprised at how
many people do not know that. Some people think if a generator passes

generator.

One method we have been discussing, which would not suffer from the
problems of key distribution is to anti-skew and hash text streams
from the Internet that change every day. The key would be a pointer
based on some combination of daily market averages. The entire system
could be memorized. In order to break it, so many different
combinations of data would have to be tried that it would literally be
impossible to keep pace with it. But most importantly, since the key
is as long as the message, there would be no way to decide if any
message was the intended one, unless the key was so poor that it
leaked the message significantly.
But the problem still remains to demonstrate in some manner that such
a scheme would actually be secure - at least in a practical manner.

If they were always there to begin with, they would not be mutable.
They would be immutable, since that is the property of something that
is always there to begin with.
Something that is always there is unchangeable, otherwise it is not
always there, but somewhere else. Anyway, the Universe is believed to
have had its origin in time, so it wasn't always there to begin with.
>Just lick your Religions God.
Whatever that means. I have no religion's God.
The Supreme Being is a metaphysical concept, not a religious concept.
Meta-physics means above-physics. It is the next rational step in
explaining reality after physics. It take what physics gives and goes
above it asking questions WHY is the physical world like what physics
describes? Physics can only do so much before it becomes a tautology.
>Just as the cause of the Universe is the Universe.
The Universe cannot be the cause of itself, because the Universe is
mutable. Therefore its essence cannot be existence. That means that it
is not the nature of the Universe just to exist.
And since the essence of the Universe is not existence, it must get
its existence from a source different from itself. That source is the
entity whose essence IS existence, called the Supreme Being.
>No we just know next to nothing about the universe. So every thing we don't know or
>don't understand we attribute to a Supreme Being.
You might, but I certainly don't. There is a clear separation between
the material world and the non-material world.

That is not an adequate argument, because it is based on the
superstitutions of ignorant people.
>PS. Don't think that I'm trying to insult your beliefs.
I do not hold the existence of the Supreme Being as a belief. I hold
it as a rational principle.
The existence of the Supreme Being is derived from the worldview of
Realism. If you accept the objective reality of external objects, as
Western scientists do, then the existence of the Supreme Being follows
rationally.
>Its just that I only believe in science.
If you really understood science you would be able to convince
yourself of the *necessity* of the Supreme Being. Physical reality
cannot be the source of its own existence because it is constantly
changing. Mutable objects cannot have existence as their essence, or
they would not be able to change.
Physics has all sorts of non-material (spiritual) entities like
quantum states, which is about as spiritual as it can get. Yet
physicists have no fundamental problem dealing with these spiritual
entites in the practice of their profession. So why all the big fuss
over a spiritual entity as the cause of everything physical?
Why rule the Supreme Being out, yet keep all these other spiritual
entities like wavevectors and vacuum fluctuations, things that have no
direct materiality? I mean, if you can handle quantum entanglement,
you can certainly handle the infinite properties of the Supreme Being.
It sounds like you are prejudiced against the existence of the Supreme
Being - a kind of spiritual bigot.

That sounds wrong to me.
Normally, temperature is sensed with forward bias on a junction.
"Diode noise" is normally generated by reverse bias breakdown. I
think these would be two different systems.
If we believe the recent Intel patent, diode noise is not even
involved. They argue that thermal-based resistive "Johnson noise" is
used. Unfortunately, the design in the patent probably cannot
demonstrate a difference even if they take the chip cryogenic.

I'm not sure how we would get validation in practice. Personally, I
would want to compress it to get some idea of the maximum possible
entropy, and ideally we might do that continuously to monitor the
quality our input data. At best it is still very rough, however.

As much as it takes.
It seems to me that trying to over-engineer what we cannot really pin
down is just asking for trouble. If we can get a better measure, then
we can cut it a bit more finely. If and when we can precisely measure
"entropy," we can produce a very efficient design.

We're talking about collecting unknowable entropy from text:
*Assuming* that the text involved is unknown (so we at least have a
chance of collecting something unknown), we still have *text*: Any
entropy value we can compute will be an average which does not
necessarily reflect the value for short segments. Different texts
will have different entropy. So we have something which is
dynamically varying and which we cannot measure accurately in the
first place. I think the situation cries out for caution.
>I so *hate* one-significant-figure answers. 8-)
We may be overstating our knowledge to imply the data are known to a
full significant figure. I wish I could do better. I am open to
suggestions.

Subject: New Encryption (I would like some analysis)
Date: Tue, 02 Mar 1999 01:05:30 GMT
Ok I just started writing my own algorithms, and I came up with what I call E
(short for encrypt). Source code is included. I would like some analysis
from professionals/amateurs. If it sucks, please tell me. It's the only way
I will learn.
It uses a 8192 byte value/position dependant key, using XOR's for the actual
encryption. The entropy of the output is high (all 256 possible symbols are
about evenly probable and distributed). Repeated chars like 'aaaa' are
encoded with different entries in the key.
Please have a look, if it's any good, it's free to use for anyone. If not,
flame me!!!
btw, I also believe that knowing the plaintext and ciphertext it's equally
improbable to make the key...

The collapse of the statevector is caused by interaction with the
environment, which includes the quantum vacuum. The Hamiltonian of the
combined system has off diagonal elements caused by the environment
which induce transistions. If the system were truly isolated, and that
includes of isolation from the vacuum (which is impossible), it would
never collaspe its statevector.
The concept of a time constant associated with transitions is tied up
intimately with the uncertainty in the energy states of a system. Time
and Energy are conjugate variables, and so they obey their version of
the Uncertainty Principle. The sharper the energy level of an energy
eigenstate, the longer the time constant for a transition from it.
For example, the ground state of an atom is infinitely sharp in energy
when not perturbed by an outside influence, so the time constant for a
transition to another state is infinitely long - that is, it is
perfectly stable.
But put it in an external electromagnetic field of the correct kind,
for example, and its spectral width is broadened such that there is
now a finite time constant associated with a transition to the first
excited state or to another state - as long as conservation of energy
and angular momentum requirements are met. When the frequency (energy)
of the disturbance is just right, the response is to absorb the
energy, which means a transition to another state.
If the state which is being perturbed is sufficiently broadened under
the influence of the perturbation, then the time constant associated
with the transition is shortened consistent with the Uncertainty
Principle - the broader the state in energy, the shorter the time to
make the transition.
You have seen things like this before in classical physics. If you get
a coin to go into a very symmretic state of oscillation, it will seem
to stay there for a long time. If you start shaking the table it is on
in a certain way, you can get it to change its mode of oscillation to
a different metastable state. The time it takes to make the transition
to the new state of oscillation depends on how precicely it is locked
into its mode of oscillation. If there is some "sloppiness" in the
mode of oscillation, it is easier to coax it into the new state of
oscillation. That "sloppiness" is the same as frequency (energy)
broadening of the state it is in.
The Uncertainty Principle has analogues in classical physics, and so
do state transitions, due to the spectral width of resonant systems.
Quantum Mechanics was not invented in a vaccum - there was a rich
heritage in classical physics from which to tap off the fundamental
concepts - with appropriate alterations to some key concepts.

I thought that the CRC would also remove correlations, by "hashing" or

Is the CRC, properly implemented, capable of removing significant
amounts of both bias and correlation, so that the keystream that
results is crypto-grade for realistic applications?

Output? If this is true as stated, then the cipher is non-existent,
since if you can reconstruct the state using only 12 known bytes of
output you can by definition select any 12 bytes of ciphertext, compute
the state it must be in, and run it backward to the start of the file,
then forward to decipher the whole thing.

Leaving us all with a tantalizing result somewhat akin to Fermat's Last

I conclude from this response that there is nothing published about your
work on the web at this point, but was anything published on paper? It
sounds to me like there is some fundamental information about
"linear-ness" and stream ciphers, which I could dimly discern by
intuition, that must be formally expressed somewhere.
Terry, I'm hoping to start a fresh and interesting discussion thread
