An algebraic geometric single key cryptosystem using stream ciphers
Ed Dawson, D. Polemi · 2002
A new single key cryptosystem is proposed based on binary algebraic geometric (AG) Goppa codes and secure stream ciphers. The system provides both security and the capability of correcting channel errors. The keystream generator is selected to provide a high level of security. The error control code provides channel error correction as well as an extra level of security by including the actual code selected as part of the key. This is distinct from previous schemes using error control codes where errors are added before transmission. We describe two models for our cryptosystem.
