异构无线传感器网络混合式密钥管理协议

Hybrid key management protocol for heterogeneous wireless sensor networks

为解决无线传感器网络的保密性问题,通过对现有WSNs密码管理方案进行整理研究,结合WSNs在资源方面的限制和传统密钥管理方案的复杂性等因素,提出一种适用于异构WSNs的密钥管理方案,即混合式密钥管理协议(hybrid key management protocol,H-KMP)方案。通过串空间形式化分析模型,验证该协议的机密性和认证性,从节点的存储和计算复杂度角度,分析其可行性,使用OMnet++软件对该方案进行仿真,得出其效率。

To solve the security problem of wireless sensor network,the existing WSNs password management scheme was studied,and combining the resource constraints and the factors of the complexity of traditional key management scheme in WSNs,a kind of heterogeneous key management scheme for WSNs was proposed,namely the heterogeneous and hybrid key management protocol（H-KMP）scheme.The strand space formal analysis model was used,the protocol was verified to be confidential and authentic.Its feasibility was verified from the computational complexity and storage node perspectives.Simulation was performed by using OMnet＋＋ software,and the efficiency of the scheme was concluded.
