Cellular Automata (CAs) is one of the most engrossing field for encrypting sensor data applied in Wireless Sensor Networks (WSN). In wireless communications, requirement of security and privacy of information is must. Therefore, transmission of sensor data over wireless communication channel plays a crucial role using cryptography techniques. The usage of cryptography characteristics of cellular automata are still not much explored in WSN. Hence in this paper, we present a symmetric key cryptography technique of block cipher using cellular automata (CAs) rules applied to sensor data in WSN. This cryptography technique uses non- complemented cellular automata rules and hybrid CA rule vector to form a group cellular automata that would be used to encrypt and decrypt sensor data. Proposed methodology has been implemented in C to validate the results.
