Crt Based Rsa Algorithm For Improving Reliability And Energy Efficiency With Kalman Filter In Wireless Sensor Networks

Broadcast authentication is a critical security service in wireless sensor networks (WSNs). However, due to resource constrained of sensor nodes, providing an authentication mechanism for broadcast message is difficult. This paper deals with the forwarding scheme for wireless sensor networks aimed at combining low computational complexity and high performance in terms of energy efficiency with RSA Cryptosystem. The proposed approach relies on a packetsplitting algorithm based on the Chinese Remainder Theorem (CRT) and is characterized by a simple modular division between integers and a Kalman filter is used to reduce the noise and find the shortest path to reach the receiving end. RSA uses the Chinese Remainder Theorem to associate the authenticating procedure of the authentication key and the Message Authentication Code of broadcast messages together. The reliability in the network and use it to allocate network resources to minimize energy while the reliability of the network is guaranteed. The Simulation is done through MATLAB which provides the data authentication using RSA cryptosystem and shows that the proposed algorithm outperforms traditional approaches in terms of energy saving with practical issues such as the effect of unreliable channels and topology changes, reliability, simplicity and fair distribution of energy consumption among all nodes in the network and finds the shortest path and also reduces the noise in the receiver end.
