与传统的无线网络基于某种确定的网络拓扑结构组织不同,动态层簇式无线传感网络(Dynamic Layer Clustered Wireless Sensor Networks,DLCN)则是通过动态层次化的方式进行组织,导致DLCN在层次簇、簇首节点选取等诸多细节,实现较为复杂,其信息加密复杂度增加,安全性和平衡性问题一直是一个难点.提出针对动态层簇式无线传感网络的信息加密算法.分析动态层簇式无线传感网络结构,计算网络节点权重跳数以及传输时延,选取最优簇首,通过Logistic混沌映射对混沌序列展开计算,结合Merlay状态机的迁移传输,输出子密钥,实现了传感信息的加密.仿真结果表明:所提算法在DLCN数据加密过程中的密文位数始终在60左右、平均密钥扩展用时在2.5 ms以下、且二值比数值更接近于1,具备较高的安全性和平衡性.
Dynamic Layer Clustered Wireless Sensor Network Information Encryption Algorithm
Unlike traditional wireless networks that are organized based on a certain determined network topology,dynamic layer clus-tered wireless sensor networks(DLCN)are organized through dynamic hierarchy,resulting in complex implementation of many details such as hierarchical clusters and cluster head node selection,leading to increased complexity in information encryption.Security and balance issues have always been a challenge.An information encryption algorithm is proposed for dynamic layer clustered wireless sen-sor networks.The structure of dynamic layer clustered wireless sensor network is analyzed,the weighted hops of network nodes and Transmission delay are calculated,the optimal cluster head is selected,the chaotic sequence is calculated through Logistic chaotic map-ping,and the encryption of sensor information is realized by combining the migration and transmission of Merlay state machine and out-putting the sub key.The simulation results show that the proposed method has consistently around 60 bits of ciphertext during the DLCN data encryption process,an average key extension time of less than 2.5 ms,and a binary ratio value closer to 1,demonstrating high secu-rity and balance.
