Turing, a fast stream cipher

Greg Rose and Philip Hawkes

Abstract

This paper proposes the Turing stream cipher. Turing offers up to 256-bit key strength, and is designed for extremely efficient software implementation. It combines an LFSR generator based on that of SOBER with a keyed mixing function reminiscent of a block cipher round. Aspects of the block mixer round have been derived from Rijndael, Twofish, tc24 and SAFER.

Note: Georny Lou pointed out an error in our derivation of the binary equivalent polynomial, corrected in this paper.
