Cartilage Matrix Assessment Using dGEMRIC,symmetric schemes. It was submitted to the call for cryptographic primitives organised by the European project NESSIE, and successfully passed the first phase of the NESSIE selection process in September 2001. In this paper, we present a cryptanalysis of SFLASH which allows an adversary provided wit

We then prove more generally that it is impossible for two parties to agree upon a shared secret in this model. This rules out many other cryptographic primitives, such as Diffie-Hellman key exchange, oblivious transfer and interactive encryption.

Simon L. Harding,Wolfgang Banzhafist-MSCPs in a permutation group and in a matrix group over a finite field. We also develop a mathematical algorithm for the MSCP in braid groups. The former implies that the usage of colored Burau representation in the key extractor causes a new weakness, and the latter can be used as a tool to investigate the security level of their KAP.

Springer Tracts in Advanced Robotics further contribution of the paper is to give an improvement to an algorithm of Galbraith for constructing isogenies between elliptic curves, and this is of independent interest in elliptic curve cryptography. We show that a larger proportion than previously thought of elliptic curves over ..155 should be considered weak.

The Structure of Spacetime Theoriesfor any Boolean function .: {0,1|. → {0,1|, no adversary can predict . from the ciphertext of . with more than 1/.. advantage; this is achieved with keys of length .+ω)(log.). In general, keys of length . yield a bound of 2. on the advantage. These encryption schemes rely on no unproven assumptions and can be implemented efficiently.
