Secure and transparent data aggregation for wireless sensor networks

Abstract

A secure and transparent data aggregation scheme for wireless sensor networks was proposed.Using hash function and XOR operation,the aggregation node completed the data integrity checking,source identity authentication and data aggregation without decrypting the encrypted data,ensured the data privacy in the process of transmitting and aggregation.Compared with related data aggregation schemes,except providing high security of encrypt key,the proposed scheme had better performances in resilient against active attack,node compromise attack and DoS attack.Also,the proposed scheme provides the information of the global data distribution.
