摘要：In this paper, we have proposed a secure data aggregation protocol for wireless sensor networks (WSNs) that is robust to deceitful nodes. The goal of this protocol is to guarantee the essential security needs (like source authentication, data confidentiality & data integrity) as well as to achieve low communication overhead and be fitted with various aggregation functions (like sum, average, max, min etc.). To achieve these security needs, it uses symmetric encryption and message authentication code (MAC). Encryption ensures data confidentiality while message authentication code ensures authentication and data integrity. An anomaly detection algorithm is used to detect the anomaly or outliers and thus prevent the deceitful- corrupted data from being contributed to the final aggregated results. Simulation results show that our protocol enhances the security of the aggregated data considerably in WSNs.
