PREFIXCODING, available at:
http://s13.zetaboards.com/Crypto/topic/..., is an
encryption scheme (with authentication) with pseudo-random
prefix codes substitution and pseudo-random transposition.
It has two kinds of processing dynamics: re-generation of
the code table and injection of dummy bits. There is a
shuffling of the plaintext string as pre-processing and a
shuffling of the byte sequence resulting from prefix encoding
as post-processing.
