摘要: 在无线传感器网络中,节点被俘获后会向网络中注入大量虚假数据。为此,提出一种途中过滤增强方案。使用加密密钥和验证密钥防止途中节点篡改数据,采用安全性增强方案解决途中节点遭到破坏而无法传递和检测数据的问题,利用备份节点的密钥验证转发数据的正确性,由此过滤虚假数据,并引入MAX_FALSE参数,消除不完全虚假数据对基站接收数据的影响。仿真结果表明,与SEF、DEF、FIMA相比,该方案的过滤能力更强,能耗更少。

Abstract: In Wireless Sensor Network(WSN), nodes will inject large amount of false data into the network if they are captured. This paper proposes an en-route filtering enhancement scheme to solve this problem. It employs encryption keys and authentication keys to prevent en-route nodes from distorting data. When en-route nodes are destroyed and can not transfer or detect data, a safety enhanced scheme is applied, which uses the encryption keys of backup nodes to validate the authenticity of transferred data and discard false ones. Parameter MAX_FALSE is introduced to eliminate the influence that incomplete false data make on the received data of base stations. Simulation results show that the scheme is more effective and energy efficient compared with SEF, DEF and FIMA.

Key words: Wireless Sensor Network(WSN), en-route filtering, false data, filtering enhancement
