Hardware Bit-Mixers

Laszlo Hars

Abstract

A new concept, the Bit-Mixer is introduced. It is a function of fixed, possibly different size of input and output, which computes statistically uncorrelated output from correlated input values, and its behavior is altered by parameters, called keys. Several constructions are presented, with very fast, power efficient implementations in electronic hardware, having very little side channel leakage. In information security bit-mixers have many applications, mostly when their output is hidden from an adversary. They include key generators, parallel stream ciphers, hash functions, data dependent authentication codes, and many more
