摘要: 传统无线传感器网络(WSN)的基站通信模型安全性较差,对资源的依赖性较强。为此,提出一种基于组密钥排他基础系统的WSN密钥管理策略(EBS-GL)。采用网络分化思想提高系统的通信效率,利用分组分层加密算法提高系统的安全性,通过汇总消息比对方法进行信息完整性认证,使用奇异点排除策略增强系统的可恢复能力。仿真结果表明,与JERT策略相比,EBS-GL可增强WSN基站的验错、纠错和排错能力,提高节点通信的安全性。

Abstract: There are many security problems in Wireless Sensor Network(WSN) on the base station model. These security problems include the low efficiency of error verification, correction and removal. Meanwhile, the information authentication has poor credibility, low communication security, and heavily depends on resource dependence. To improve the security of such network, an grouping and layered key management strategy in WSN based on Exclusion Basis System(EBS) which named EBS-GL is proposed. This model employs technologies such as network decoupling, a novel grouping and layered information encryption algorithm, the information integrity authentication mechanism, and the strategy of removing singularity. Simulation results prove that this model has stronger abilities of error verification, correction and removal of base stations than JERT strategy.
