Timestamp Based Authentication Protocol for Smart Card Using ECC

摘要

Elliptic Curve Cryptography is one of the most suitable public key techniques for its small key size and high security and is suitable for secure access of Smart Card. Smart Card based authentication plays a critical role in communication network as they are using embedded processors where resources such as storage, time or power are constrained. We propose a timestamp based ECC authentication protocol which produces multiple session keys during communication in constrained environment to enhance the security. The proposed protocol is efficient as it has improved the performance timings of basic operations like key generation, signature generation / verification.
