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 有限以及传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适用于WSNS节点的数据加密.Traditional encryption schemes are not suitable for the Wireless sensor networks (WSNS) due to some intrinsic features of nodes in WSNS such as low energy, limited computation ability and storage resources. This paper presented a novel block encryption scheme based on hybrid chaotic maps dynamically and proposed an integer digital random method, and the Feistel network structure, which is a kind of fast, secure, low resource consumption and suitable for WSNS nodes encryption scheme. The experimental tests show the new encryption scheme has follows prefect performance: the large key space, very good diffusion and disrupt performance, strict avalanche effect, excellent statistical balance and fast encryption speed of the new scheme, and the encryption scheme passes the SP800-22 test; meanwhile, the analysis and testing of speed, time and storage space on the simulator platform shows this new encryption scheme is well able to hide the data information the node in WSNS.
