A Homomorphic MAC-based Secure Data Aggregation Scheme for Wireless Sensor Networks

A Homomorphic MAC-based Secure Data Aggregation Scheme for Wireless Sensor Networks

A Wireless Sensor Network is composed of a large number of wireless sensor nodes and usually deployed in unattended environment to collect target information. At present, WSN is facing a growing range of security threats owing to its wireless and resource-constrained characteristics. Compromised sensor nodes can easily corrupt data accuracy and integrity by falsifying sensed information, selectively forwarding or misdirecting received data packets during the process of data aggregation. To solve these security problems, we propose a homomorphic MAC-based secure data aggregation scheme for WSNs (HMSDA) that can provide adequate protection of data confidentiality and integrity for wireless sensor networks. The simulation results indicate that HMSDA can effectively identify the tainted data in the process of data aggregation.
