摘要
针对无线传感器网络中现有的分组加密算法的优缺点,根据无线传感器网络安全需求提出了一种基于混沌S盒的分组加密算法。主要利用了混沌的非周期性、不可预测性等相关特性生成随机数,利用随机数设计对应的S盒,通过统计性检测对其安全性进行分析,并通过能耗仿真对其可用性进行分析,与RC5、RC6加密算法进行比较,结果表明该算法在无线传感器网络加密算法中有一定优势。
The pros and cons of the existing encryption algorithm for Wireless Sensor Network（WSN） were analyzed.A chaotic block cipher based on chaos box was proposed for WSN in accordance with its security request.Random number was generated by mainly using the chaotic aperiodicity,unpredictability and other related characteristics,and corresponding S box was designed by using random number.Finally,conclusion was made by comparing RC5 and RC6 at statistical performance and energy consumption.The results show this encryption scheme has better performance for WSN.
