RadioGatún, a belt-and-mill hash function.

Abstract

We present an approach to design cryptographic hash functions that builds on and improves the one underlying the Panama hash function. We discuss the properties of the resulting hash functions that need to be investigated and give a concrete design called RadioGatun that is quite competitive with SHA-1 in terms of performance. We are busy performing an analysis of RadioGatun and present in this paper some preliminary results.
