Klimov and Shamir proposed a new class of simple cryptographic primitives named T-functions. For two concrete proposals based on the squaring operation, a single word T-function an...
A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...
Abstract. The security of the alleged RC4 stream cipher and some variants is investigated. Cryptanalytic algorithms are developed for a known plaintext attack where only a small se...

Abstract. Since Crypto 2004, hash functions have been the target of many attacks which showed that several well-known functions such as SHA-0 or MD5 can no longer be considered sec...
Abstract—Fast stream ciphers are used extensively for encrypted data transmission in mobile networks and over multigigabit links. CryptMT, a recently proposed stream cipher, is o...
