摘　　要：本文针对无线传感器网络传感器节点处理能力弱、携带能量低的特点,提出基于Rijndael算法优化的数据加密技术.通过对Rijndael加密算法的数据存储、列混合以及轮变换等特点的分析,提出对于加密算法的优化建议,采用可编程逻辑器件对优化后的加密算法进行设计和实现,并进行加密验证,同时对优化后加密算法的数据处理速率、算法功耗、逻辑资源占用情况进行评估.由实验结果可知,优化后的Rijndael加密算法相比优化之前有很大的突破,能够适用于无线传感器网络的数据加密.Considering the sensor node of wireless sensor network weak processing and carrying low en- ergy, this paper gives the optimized Rijndael algorithm data encryption technology. Based on the analysis of Rijndael encryption algorithm of data storage, columns, the characteristics of the mixing and round trans- formation, optimization algorithm is suggested .The programmable logic devices is used for the design and authentication of the optimized encryption. At the same time the data processing speed, power and logic resource usage of the optimized encryption algorithm is evaluated. The experimental results shows that the optimized Rijndael encryption algorithm has a great breakthrough and can be applied to the wireless sensor network data encr^otion.
