Turing: A Fast Stream Cipher

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 [21] with a keyed mixing function reminiscent of a block cipher round. Aspects of the block mixer round have been derived from Rijndael [6], Twofish [23], tc24 [24] and SAFER++ [17].
