鉴于无线传感器网络(WSN)对加密算法高效性和安全性的要求,设计一种轻量级的混沌分组加密算法,并提出了安全性更高的动态子密钥扩展方案。该方案依托WSN云服务器的强大数据运算和处理能力,利用新的加解密机制,将子密钥同步任务转移到云服务器进行处理,大幅降低节点的运算负担。实验结果和性能分析表明,该方案具有较好的扩散混乱特性和统计平衡性,且密钥安全性强、算法效率高,在WSN通信加密领域具有良好的应用前景。
In view of high efficiency and security requirements in WSN encryption algorithm,a lightweight chaotic block encryption algorithm was designed and a novel scheme of dynamic sub keys extension was proposed.To greatly reduce the computing burden of WSN nodes,this scheme made full use of WSN cloud servers monitoring platform,which was powerful in data computing and processing,and transfered the sub keys synchronization task from nodes to cloud servers.Experimental results and performance analysis show that the scheme has good characteristics of diffusion,confusion and statistical balance,strong key security and high algorithm efficiency.It has a good application prospect in the field of WSN communication encryption.
