Practical Attacks on AES-like Cryptographic Hash Functions
Despite the great interest in rebound attacks on AES-like hash functions since 2009, we report on a rather generic, albeit keyschedule-dependent, algorithmic improvement: A new …
Differential Cryptanalysis of Keccak Variants
In October 2012, NIST has announced Keccak as the winner of the SHA-3 cryptographic hash function competition. Recently, at CT-RSA 2013, NIST brought up the idea to standardize …
Practical Attacks on the Maelstrom-0 Compression Function
In this paper we present attacks on the compression function of Maelstrom-0. It is based on the Whirlpool hash function standardized by ISO and was designed to be a faster and more …
