Abstract

This paper advocates a new hash function family based on the HAIFA framework, inheriting built-in randomized hashing and higher security guarantees than the Merkle-Damgård construction against generic attacks. The family has as its special design features: a nested feedforward mechanism and an internal wide-pipe construction within the compression function. As examples, we give two proposed instances that compute 256- and 512-bit digests, with a 8- and 10-round compression function respectively.
