Abstract :
User authentication is most essential to prevent the unauthorized adversaries from obtaining the system resources. This paper proposes a cellular automata based remote-user authentication (CARA) scheme to reduce the complexity of encryption and hash-based cryptosystems. CARA uses cache-based nonce to avoid synchronization problems and thwart replay attacks. This scheme is robust against other attacks as well. The inherent parallelism of cellular automata provides for its fast implementation
