This paper proposes a construction for collision resistant 2n-bit hash functions, based on n-bit block ciphers with 2n-bit keys. The construction is analysed in the ideal cipher mo...

We initiate a study of on-line ciphers. These are ciphers that can take input plaintexts of large and varying lengths and will output the ith block of the ciphertext after having p...

Abstract. The cipher family SPEED (and an associated hashing mode) was recently proposed in Financial Cryptography '97. This paper cryptanalyzes that proposal, in two parts: F...

Constructions for hash functions based on a block cipher are studied where the size of the hashcode is equal to the block length of the block cipher and where the key size is appro...
