A paper of mine just went up on http://eprint.iacr.org/ It has some ideas
that I hope are new, I think are good, and I know are unorthodox. I'm well
aware of the usual fate of such innovations, especially from amateurs.
If anyone would like a break from looking at new hashes, perhaps they
could have a look.

Title Exploring Cipherspace: Combining stream ciphers and block ciphers
Abstract:
This paper looks at the possibility of combining a block cipher and a stream
cipher to get a strong hybrid cipher. It includes two specific proposals for
combining AES-128 and RC4-128 to get a cipher that takes a 256-bit key
and is significantly faster than AES-256, and arguably more secure. One is
immune to algebraic attacks.
