Integer Matrix Keys for Secure Data Aggregation in Clustered Wireless Sensor Networks

Providing Privacy and security for aggregated data in wireless sensor networks has drawn the attention of practicing engineers researchers globally. Several cryptographic methods have been already proposed to solve integrity problems data. Matrix cryptography is a better option creating secure encryption/decryption algorithms counter quantum attack. However, these higher computational cost increased communication overhead. Hence, new technique loss-less aggregation Clustered Wireless Sensor Networks presented. The method uses integer matrices as keys integrity. operations are carried out finite field Z p . Loss-less extended homomorphic summation while cipher text expansion ratio kept substantially low. algorithm inbuilt fast efficient signature verification facility. execution time our mechanism found be approximately 50 percent less compared couple standard existing schemes.
