物联网感知层安全簇维护方法

分簇结构的物联网感知层得到了广泛应用,针对大量分布的传感器节点的脆弱性、通信开放性和无人值守等特征使得其面临着越来越多的安全威胁,提出了一种物联网感知层安全簇维护方法,通过加密认证、节点测评和按需维护机制来保护簇的安全稳定运行.基于NS2的仿真实验结果表明,所提出的物联网感知层安全簇维护方法能低能耗地有效抵御假冒攻击、簇头占据攻击和针对数据包的攻击,保证簇结构的稳定和安全.

Methods of secure clusters maintenance for the sensing layer in the internet of things

Clusters-based structure of the sensing layer in the Internet of things has been widely applied. A large number of distributed sensor nodes are facing more and more threats because of their properties in vulnerability, open communication,unattended feature. A method of secure clusters maintenance for the sensing layer in the Internet of things is proposed,which protects the security and stability of clusters by means of encryption and authentication, evaluation of node's credibility and maintenance on demand. The simulation results based on NS2 show that the proposed method can effectively deal with possible attacks such as node personating, cluster-head occupying, and packets attacks, make sure the structure of clusters stable and secure by relatively less consumption of energy.
