Abstract
A method and apparatus for simple identification and signature which enable any user to prove his identity and the authenticity of his messages to any other user. The method and apparatus are provably secure against any known or chosen message attack if factoring is difficult, and require only 1% to 4% of the number of modular multiplications previously required. The simplicity, security and speed of the method and apparatus derive from microprocessor-based devices which may be incorporated into smart cards, personal computers, passports, and remote control systems.
