Secure data aggregation in wireless sensor networks

摘要: In-network data aggregation is an effective method to reduce the amount of transmitted and therefore saves energy consumption in sensor networks. However, adversary may compromise some nodes, use them forge false values as result. Previous secure schemes have tackled this problem from different angles. The goal those algorithms ensure that Base Station (BS) does not accept any forged results. Based on our survey existing research efforts for ensuring aggregation, a novel approach uses homomorphic encryption Message Authentication Codes (MAC) achieve confidentiality, authentication integrity wireless networks proposed. Our experiments show proposed significantly reduces computation communication overhead.
