Abstract :
In this paper, we evaluate the performance of our Advanced Two Tier User Authentication (ATTUA) scheme [5] which is proposed for heterogeneous Wireless Sensor Networks. ATTUA scheme employs both Public Key Cryptography (PKC) and Secret Key Cryptography (SKC) approaches, such that it takes advantage of both schemes. Our analysis and simulation results have shown that, ATTUA scheme is not only more secure and yet scalable than existing SKC based schemes, but also requires less processing power and provides higher energy efficiency than existing PKC based schemes.
