无线传感器网络安全数据融合研究

数据融合去除冗余信息，延长网络生命周期，有效地缓解了无线传感器网络资源瓶颈的问题。但是，无线传感器网络经常部署在开放的甚至敌对的环境中，使其安全问题非常突出，数据融合在具体实施过程中，极易受到安全攻击。因此，安全数据融合协议的设计成为无线传感器网络安全最为基本且重要的研究领域。文中分析了无线传感器网络数据融合面临的攻击种类和安全需求及挑战，着重比较了近年来该领域具有代表性的安全数据融合协议，指出了该领域今后的研究热点。

Research on Secure Data Aggregation in Wireless Sensor Network

Data aggregation eliminates redundant information,increases the lifetime of the network and effectively relieves the limit-re- source problem in wireless sensor network. However, wireless sensor network（WSN） is usually deployed in open area, particularly in the hostile area,its security issue is very prominent,in the implementation of data aggregation in WSN,the data is prone to security attacks. Consequently, the design of secure data aggregation protocols is one of the most important aspects and basic research field of security wireless sensor network. It analyses various attacks, security goals and challenges in wireless sensor network data aggregation, then com- pares the recent representative secure data aggregation schemes. The future research direction is summarized.
