面向无线传感器网络的混沌加密与消息鉴别算法

         

摘要

As for the traditional digital chaos-based scheme being not directly applicable for WSN because some sensor node does not support the float type of computation, integer chaotic maps and its block encryption schemes are firstly in-troduced, and then a novel chaos-based message authentication code (MAC) scheme was proposed, which was length changeable with high-level hybrid chaotic security. At last, a security application solution for data communication on WSN employing the proposed chaos-based schemes is presented, and the performance evaluation on the real-world Mi-ca2 node is analyzed to show that the new security solution is more applicable for WSN than the current most popular security scheme, TinySec.%  针对数字混沌密码无法直接在轻量的传感节点上实现,介绍了一种基于整数型混沌映射的轻量级分组加密算法,并提出一种新型的消息鉴别码方案,具有输出长度可变、混沌序列复合安全等特点,最后实现了一个完整的无线传感网数据安全传输应用方案,并在 Mica2节点上给出性能分析。实验表明该方案对无线传感网具有更高的实用性。
