Turing is a new, fast, stream cipher. It
is experimental, and may or may not be secure. Version 1.8 (of TuringRef.c)
should be considered to define the cipher.
Turing.tgz
is a gzipped tar archive of the various implementations. Note that I use
8-character tabs but a 4-character indent. Included are a generic test
harness, a reference implementation, a faster implementation using table
lookups, a very fast implementation using all inline code, and an
intermediate version that uses lazy evaluation to fill the Sbox tables
(both key agile and reasonably fast).
TuringPres.pdf
(240k) is the full presentation originally prepared for the rump session of
Crypto2002 (27 slides, only 1 of which was shown). It's been updated to be
consistent with the source code.
Turing.pdf
is a full paper about the final design. (Accepted to Fast Software
Encryption 2003.)
Erratum: Georny Lou pointed out to us
that the binary polynomial shown in the paper was incorrect. The paper
above has been updated to show the correct binary equivalent polynomial.
