Network Security System with Optimized Randomized Multiple Key Exchange Algorithm

Abstract

This paper illustrates three different algorithms to provide shared secret key for security of the system. The proposed three algorithms namely 1) Modified Simple Password Key Exchange Scheme 2) Modified Diffie-Hellman Key exchange Scheme 3) Modified Elliptic Curve Scheme are meant to provide shared secret key for authentication process. Enhancements in terms of memory requirement, storage and other security properties such as authentication among mutual users, fraud prevention, attack etc., prove the validity of the proposed algorithms in proving authentication for the cryptographic identification of networks.
