Cellular Automata Based Secured Data Transmission Technique in Wireless Sensor Networks

Abstract

In Wireless Sensor Network (WSN), CA to based mechanism is used to reduce various optimization problems (energy consumption, network life time, coverage, connectivity, security etc. with simple rules (algorithms). Due to this reason many researchers have concentrated on CA for improving the overall performance in WSN. Therefore, transmission of sensor data over wireless communication channel plays a crucial role using the cryptographic technique. The CA based crypto system is shows high quality of randomness of pattern. We can increase the quality of randomness by implementing the PCA(Programmable Cellular Automata).The sensor data must be encrypted by using Rule based symmetric key Encryption Algorithm(RSE). The proposed technique is based on the encryption algorithm & decryption algorithm by using dynamic cellular automata rules provides good security for sensor data in WSN.
