CHOOSING IDEAL PARAMETERS FOR ZERO-KNOWLEDGE AUTHENTICATION PROTOCOLS AND COMMUTATIVE CIPHERS

It has been proposed a method for commutative encryption and zero-knowledge two-step protocols with a special choice of parameters for this cryptoschemes. Advantage of the method is eliminating weak messages in case of commutative encryption and simplification of zero-knowledge protocols.
