摘要
WSN是一种节点资源受限的无线网络,其链路层安全策略的轻量化研究适合于各种应用环境的WSN系统,且效果显著。结合序列密码和分组密码各自的优势,提出了一种新型轻量的WSN链路层加密算法—TinySBSec。对算法的安全性进行了理论分析,并且采用统计学方法,对该算法的安全性能进行了测试,结果证明算法具有良好的安全性能。
WSN is a kind of wireless network with constrained node resources. The research on the security strategy of the lightweight link-layer is appropriate for the WSN systems working under various kinds of application environ-ments;in addition, the effects are marked. This paper describes a new lightweight WSN link-layer encryption algo-rithm based on the advantages of the stream cipher and block cipher. The security strategy of the new algorithm was analyzed and the new algorithm was tested by using statistical methods. The results show that the new algorithm has good safety performance.
