Title: The CSQUARE Transform

Abstract: In this paper we show how to combine the design concepts of the
SQUARE and CS block ciphers to produce a pseudo-random permutation CSQUARE
suitable for use in block cipher and hash design with a very high
multi-round trail weight. The new design inherits the hardware efficiency
of the SQUARE linear transform pattern as well as the efficiency of the fast
pseudo-Hadamard transform over a finite field. We demonstrate the DMWT hash
function which makes use of our new results.

Note: It's a draft and work in progress. I appreciate all comments,
critiques, etc...

Thanks,
