Whereas a block cipher enciphers messages of some one particular length the blocklength , a variable-input-length cipher takes messages of varying and preferably arbitrary leng...

This paper discusses the security of a leakage-resilient stream cipher presented at FOCS 2008, instantiated in a practical setting. Based on a case study, we put forward implementa...

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...

Abstract. Online ciphers are deterministic length-preserving permutations EK : ({0, 1}n )+ → ({0, 1}n )+ where the i-th block of ciphertext depends only on the first i blocks of...

Abstract. We evaluate constructions for building pseudo-random functions (PRFs) from pseudo-random permutations (PRPs). We present two constructions: a slower construction which pr...
