An Investigation of Optimal Design of Source Anonymous Message Authentication Scheme using Analytical and Computational Approach

One of the most effective techniques to prevent the tainted and adversary messages from being forwarded in wireless sensor network is message authentication. Message authentication is a short piece of information used to offer integrity, validate a message and legitimacy declarations on the message. In this paper, we have used the Source Anonymous Message Authentication scheme (SAMA) that is on the basis of elliptic curve to provide better security. Here we are using a hashing function (SHA-256) for signature generation and verification at the transmitter and receiver end which is on the basis of acceptance or rejection of the messages. SAMA technique allows nodes to authenticate messages for the purpose of saving sensor power provided source node privacy, resilience to node attacks and eliminated the problem of threshold of number of messages at the sending and the receiving end. We have evaluated SAMA and polynomial techniques in MATLAB (R2014a) instead of ns2 simulator that gives us better results in less time as compared with the previous technique and also analyzed SAMA and polynomial techniques at the transmitter and the receiver end differently.
