摘要
针对无线传感器网络中存在的节点能量与存储运行空间资源有限、计算量过大等问题,为提高无线传输过程的安全性,需采用随机性强、安全性高、占用内存小的加密算法。根据仪表行业对加密算法的要求,对行业标准推荐使用的3DES与AES这2种加密算法进行了研究比较。通过对其密钥空间、线性复杂度、信息熵及"0-1"平衡性等性能的比较可知,AES算法优于3DES算法,更适用于无线传感器网络的数据加密。
Because of the resources limited of wireless sensor network （WSN） ,e . g. ,the node energy and storage and operation space, excessive calculation; in order to enhance the security of wireless transmission process limited, it is necessary to use encryption algorithm with strong randomness,high security,and small memory occupation. Based on the requirement of encryption algorithm for household instrument industry, two kinds of encryption algorithms that are recommended by industrial standards, i. e. 3DES and AES are compared. Through comparing the performance of key space, linear complexity, information entropy and balance for two algorithms, it is found that the AES algorithm is better than3DES algorithm, and more adapted to data encryption of WSN.
