摘　　要：致力于如何实现无线传感器网络的安全数据融合,提出了一种基于模式码的安全数据融合协议———SPDAA(Securepattern-based data aggregation and authentication)。该方案在节点的感应阶段采用差值比较法确定参与会话的节点,并采用基于两跳的认证技术在数据融合阶段进行数据(模式码)的认证,保证数据的完整性,避免了由于盲目拒绝虚假节点而造成的数据丢失。同时该方案考虑增加能量因子,有效地均衡了整个网络的能耗。仿真结果表明:SPDAA能够有效避免重要数据的丢失,保证网络数据高效安全性,均衡网络能耗,延长网络生存时间。This paper is committed to realize the security of data fusion,it presents a new protocol that provides secure aggregation for wireless sensor networks,which is called--SPDAA （Secure pattern-based data aggregation and authentication）. In the node sense stage, each node compares its data with the value which is set before. SPDAA is based on a two hops verification mechanism of data integrity,which allows to avoid referring to the base station for data integrity verification. Hence, it minimizes the blind rejection of sensed data. The scheme also considers of the energy factor which effectively balanced the energy consumption of the whole network. The simulations results show that the proposed protocol yields significant savings in energy consumption while preserving data integrity.
