Abstract. Thwarting unlawful redistribution of information sold electronically is a major problem of information-based electronic commerce. Anonymous fingerprinting has appeared a...
Since many applications require the verification of large sets of signatures, it is sometimes advantageous to perform a simultaneous verification instead of checking each signatu...
We describe the design of Yarrow, a family of cryptographic pseudo-random number generators (PRNG). We describe the concept of a PRNG as a separate cryptographic primitive, and the...
Abstract. In recent years, three main types of attacks have been developed against Feistel-based ciphers, such as DES[1]; these attacks are linear cryptanalysis[2], differential cr...
For the most compelling applications of threshold cryptosystems, security against chosen ciphertext attack is a requirement. However, prior to the results presented here, there ap...
