针对无线传感器网络(WSNS)中节点配备的能源少、节点计算能力低、存储资源有限以及化统的加密方法不适用于WSNS中等问题,提出了一种新的基于动态迭代的混合混沌方程及其整型数值化方法.并结合Feistel网络结构设计了一种快速、安全且资源消耗低的适用于WSNS节点的分组加密算法.通过对混合混沌分组加密算法进行了大量的实验测试之后,发现该算法具有密钥空间大、严格的雪崩效应、扩散及扰乱性高以及均等的统计平衡性等优点,同时该算法还成功地通过了SP800-22的严格测试;算法经过仿真器平台上运行的速度、时间及所占存储空间的测试分析,结果表明设计的混合混沌分组加密算法是完全能够通用于WSNS节点的数据加密.
Aiming at the problems of WSNS, such as less energy, less computing power, limited memory resources and ineffective encryption methods for WSNS, this paper proposes a new hybrid chaotic equation based on dynamic iteration and its Integer numerical method.With the Feistel network structure, a fast, secure and low resource consumption packet encryption algorithm for WSNS nodes is designed.After a lot of experiments on the hybrid chaotic packet encryption algorithm, it is found that this algorithm The algorithm has the advantages of large key space, strict avalanche effect, high diffusion and disruptiveness, and equal statistical balance. At the same time, the algorithm successfully passes the rigorous testing of SP800-22. The algorithm runs through the simulator platform, Time and occupied storage space. The results show that the hybrid chaos-based packet encryption algorithm designed can be used universally for WSNS node data encryption.
