An Efficient Two-Factor Remote User Authentication and Session Key Agreement Scheme Using Rabin Cryptosystem

In this paper, we present a safe and reliable remote user authentication and session key agreement scheme using the Rabin cryptosystem. The Rabin cryptosystem relies on prime integer factorization, which provides high security. Our scheme is validated using the Burrows–Abadi–Needham logic, which proved that it facilitates mutual authentication and session key agreement securely. The informal security analysis shows that the proposed scheme is secured against various malicious attacks. We simulate our scheme using the well-known Automated Validation of Internet Security Protocols and Applications tool, which confirms that the proposed scheme can defend from the passive and active attacks and also prevents the man-in-the-middle and replay attacks. Further, the performance evaluation shows that our scheme provides robustness against various security attacks as well as efficient in the terms of smart card storage cost, estimated execution time, communication cost and computation cost.
