I am a mathematician, computer scientist, cryptology consultant, computer programmer, and patent agent. I am available if you need an expert opinion on a cryptosystem or a patent. Often some money paid for analysis in advance can save a lot of money and trouble later. Contact me for details.
I wrote the crypto engine for these InformationSecurity products. For general information on cryptology, see my Crypto Mini-FAQ.
I also wrote Eureka/Mercury, a PC equation solver.
Paper: I have some writings here.
