Hi,all, maybe I post a non-sense topic.But when I learned zero-
knowledge proof, I wonder why there is nothing about semi-knowledge
proof,or maybe quantitive-knowledge proof? Then I came to the
literature,I only found something about knowledge complextiy of proof
writen by Bellare and Goldreich.
In an interactive proof system,a zero -knowledge proof system require
the prover give nothing about witness via proving something
validly .Maybe we can define semi-knowlege proof system as
following :When the prover proves something, We allow the prover leak
some knowledge to the verifier, but not the hardcore knowledge.Maybe
this form of semi-knowledge proof is equal to zero-knowledge proof
with auxiliary input.But in some situations ,
these two notions are not same.Maybe we can improve the...

Hi,
I would like to know if make sense the statement "Reversible hashing".
I mean is possible to develop a hash algorithm, or better a digest
algorithm, (variable input lenght, fixed output lenght) that do not
respect the rule to be one-way. I don't want to compare with other
hash algo such SHAx, MDx ecc... but, it can be done?
Just for curiosity; I think this question can be some kind of
interesting discussion, I am wrong?

Oh, sorry for my bad english ;-).

Cheers,
Federico.

Hello,

I am a 20 year old german student and hobby cryptographer, with
strong interests in public key algorithms, cryptographic protocolls
and cryptanalysis. In the year 2003 I came up with a new signature
scheme based on the closest vector problem. This scheme was successfully
presented at germans biggest youth science fair "Jugend Forscht" and one
year later at the Intel ISEF (International Science and Engineering Fair)
in Phoenix, Arizona.

By now, I have not only added an public key encryption algorithm but
also analyzed the algorithm for weaknesses. Hence, the time has come,
where this algorithm has to be presented to a great audience to analyze
it even further.

Here is a first small (and simplyfied) overview: In order to get a
new type of public key encryption algorithm, that is not based on the
factoring problem or the discrrete logarithm in finite fields, we have
to find a suitable hard mathematical problem.

ACM Digital Rights Management Workshop 2007

October 29, 2007, Alexandria VA, USA
Collocated with ACM-CCS 2007

Early Registration deadline: October 8, 2007

ACM-DRM is an international workshop that looks at the DRM
problem in its broadest possible interpretation and aims to bring
together scientists and scholars from all the related disciplines
for an exchange of ideas and presentation of cutting edge results
related to digital content distribution.

This year, the program committee compiled a strong program
covering many aspects of DRM related research including
software protection, system architectures, legal aspects and
supporting technology.

VRL-1 nerve-endings -- in which
those VRL-1 functions as thermal pain receptors -- should be scorched
with smokeless, charless, sootless, ashless, emberless, non-toxic,
clean, non-polluting, orangish-yellow oxyacetylene flames until his/
her body is completely dehydrated from the flame's heat.** [See notes

The flame burn injuries will cause severe dehydration and loss of
blood volume by heating up the skin's water and causing it to
evaporate. Shock sets in as the blood continues to thicken. After 2
immeasurably-long hellish hours the hipcrime scumslime will most
likely die. The sick f--k will be in SO much pain and distress yet
totally unable to express any hint of it; not even a single tear drop
will be shed from his/her eyes. Such cold-hearts deserve such fates.
It's called "eye for an eye."

Hi,

I need to typeset (latex2e) a series of articles containing very large
numbers that don't fit on any-sized line. They typically have 300 to 1000
decimal digits. This is within the range of numbers commonly used in
cryptography, hence the posting here.

What I'm looking for is a (preferably math mode) macro to typeset them in a
convenient and readable way, something like:
| <-- right margin
x = 123 1234567890
1234567890 1234567890 1234567890 1234567890 1234567890
1234567890 1234567890 1234567890 1234567890 1234567890

The splitting at every 10 digits (from the right) seem appropriate in such
case. The "x = " part can be any formula.

I know this has already been done, since I've read articles using such
formatting. I just can't remember which article/author. Someone on a tex
group offered me a handcrafted almost complete solution, but I wonder
whether something more standard and polished is available.

She can frighten the lean block and facilitate it in favour of its

Many audiences honestly pose the continued market. Sayed, still
