摘　　要：针对无线传感器网络(WSN)中容易受到的攻击的问题,提出一种新的基于路径序列检测的安全机制。该机制通过构建合理的路径序列并进行安全验证来实现数据包的路由规则检测及上一跳节点的身份认证,保证路由规则的正确性和数据的真实性。经过性能分析和仿真实验表明该机制在网络规模增加的情况下攻击检测失效的概率不会降低,所提策略能有效地检测出恶意篡改数据传输路径的路由攻击,提升无线传感器网络的安全性。To the problem of vulnerable to be attack in Wireless Sensor Network （WSN）, a new security mechanism based on path sequence detection was proposed in this paper. This mechanism could detect the routing rule of packets and achieve the authentication of previous hop through constructing reasonable path sequence and sequence verification, then the correctness of routing rule and authenticity of data could be guaranteed. Performance analysis and simulation results show that the probability of the failure of data transmission path attacks detection will not decrease with the network scale. This result demonstrates that the proposed mechanism can effectively detect tampering of data transmission path attacks and can improve the security of the wireless sensor network.
