On error exponents for arbitrarily varying channels
- …Abstract- The minimum probability of error achievable by random codes on the arbitrarily varying channel (AVC) is in-vestigated. New exponential error bounds are found and applied to the AVC with and without input and state constraints. Also considered is a simple subclass of random codes, called ra…

Undeniable Signature Schemes Using Braid Groups, Preprint arXiv: cs.CR/0601049
- …Artin’s braid groups have been recently suggested as a new source for public-key cryptography. In this paper we propose the first undeniable signa-ture schemes using the conjugacy problem and the decomposition problem in the braid groups which are believed to be hard problems.…
