本文针对WSN对数据安全传输需求，提出了一种新的WSN数据加密方案。该方案基于 RC4加密算法，在密钥调度算法（ KSA）阶段引入混沌信号。该算法结合了对称加密算法与混沌理论，对称加密算法加密速度快，占用资源少。并用C语言实现了本文提出混沌 RC4加密、与RC4、RC5算法在执行速度、占用空间，字符频率等方面进行了比较，发现混沌RC4加密算法虽然占用空间稍大，但执行速度低于 RC5算法，解决了RC4的安全缺陷，适用于无线传感网络。

In this paper, we propose a new WSN data encryption scheme for WSN security demand. The scheme based on the RC4 encryption algorithm, we involve the chaotic signals to the key scheduling algorithm (KSA). The algorithm combines a symmetric encryption algorithm with chaos theory, symmetric encryption algorithm is faster, uses less resources. We use C language to implement the chaotic RC4 encryption ,and compare with RC4, RC5 algorithm in execution speed, space , and so on. We found although the chaos RC4 encryption algorithm space is slightly larger, but execution speed is faster than RC5 algorithm, it can be applied to wireless sensor networks.
