摘　　要：针对现有无线传感网络(wireless sensor networks,WSN)群组通信中网络环境复杂、资源占用率高以及共谋攻击等问题,提出一种融合三元多项式和EBS(exclusion basis system)管理机制的动态密钥管理方法。通过分析现有方法的不足,从WSN系统模型和EBS密钥管理2个方面对其进行改进,针对WSN系统模型引入层次式拓扑结构,有效解决簇头节点存在的单点失效问题,在此基础上,根据EBS群组密钥管理方法,引入三元多项式算法对EBS管理机制的参数进行优化。仿真结果表明,改进方法与局域化组合密钥管理(localized key management,LOCK)方法相比,改进后的EBS方法可以减少传感器节点的密钥存储量,增加网络共谋链的长度以及提高WSN的网络抗毁性。Aiming at solving the problems of complex network environment,high resource utilization and collusion attacks in existing wireless sensor networks(WSN)group communication,a dynamic key management method combining ternary polynomials and exclusion basis system(EBS)management mechanism is proposed.This paper improves the existing method in two different aspects:the WSN system model and EBS key management.It introduces the hierarchical topology structure for WSN system model and effectively solves the single point failure problem of the cluster’s head node.Based on the EBS group key management method,the ternary polynomial algorithm is introduced to optimize the EBS management mechanism parameters.The simulation results show that,compared with the localized key management(LOCK)method,the improved EBS method can increase the length of the collusion chain while the sensor nodes store less keys,and improve the survivability of the WSN.
