摘要
随着无线传感器网络(WSN)的发展,安全需求逐渐增加。文中设计一种基于高级加密标准(AES)的改进型加密算法。该算法充分考虑了WSN的分布式特性,通过设计多个S盒来增强算法的安全性。同时利用多节点协同等方式将计算复杂性集中在具有强大计算能力的基站终端上,精简了节点的工作量。运用该算法结合实际需求,设计出3种无线网络加密方案,3种新方案的仿真结果证明了该算法具有灵活多变、传输速度快、计算代价低的优点,同时还能更加有效地保证数据安全。
With the development of wireless sensor networks(WSNs),security requirements have gradually increased.An improved encryption algorithm based on the advanced encryption standard(AES)designed in this paper.The distributed characteristics of WSN are fully considered in the algorithm.Multiple S-boxes are designed to enhance the security of the algorithm.The multi-node coordination and other patterns are utilized to focus the computational complexity on base station terminals with strong computing capabilities,so as to reduce the workload of the nodes.In combination with actual needs,three wireless network encryption schemes were designed by means of this algorithm.The simulation results of three new schemes prove that the algorithm has the advantages of flexibility,fast transmission speed,and low computational cost,and can also ensure data safety more effectively.
