Turing (cipher)

Turing (cipher)

Turing is a stream cipher developed by Gregory G. Rose and Philip Hawkes at Qualcomm for CDMA. It is designed to be fast in software and achieves around 5.5 cycles/byte on some x86 processors.

Turing generates 160 bits of output in each round by applying a non-linear filter to the internal state of an LFSR.
