Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...

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 security of iterated hash functions relies on the properties of underlying compression functions. We study highly efficient compression functions based on block ciphe...

We put forward a new model for understanding the security of symmetric-key primitives, such as block ciphers. The model captures the fact that many such primitives often consist of...
