Many people have been talking about cryptographic applications in hardware on the list. I suspect these will be largely untapped until a chip that does general-purpose RSA encryption comes along. There are many DES implementations that could be integrated with such a chip and then worked into computer cards, telephones, cryptography kits, etc. Does anyone know of the existence of an RSA chip? To the best of my knowledge they do not exist. Are there any plans for an RSA chip? The chip would ideally *not* be constrained to work with DES, or at least the DES encryption would be an option in addition to just pure RSA encryption of arbitrary data, for reasons of potential insecurity in DES and emergence of other superior algorithms (which upon appearance would not automatically make a general-purpose chip obsolete).
