摘　　要：针对认证加密算法在实际应用中难以生成选择明文攻击的不可区分性问题,结合硬件算法平台,应用数据包标志序号、动态可调密钥计数器等提出一种改进的可调认证加密方案。通过增加小规模硬件部件换取可调因子与加密的并行计算,支持受资源限制嵌入式设备应用,可实现算法在网络中的平稳运行。实验结果表明,该方案通过并行计算可缩短系统的运行时间,提高系统的整体运行效率。The authentication encryption algorithm is difficult to generate the indistinguishability of Chosen Plaintext Attack(CPA)in practical application.Therefore,an improved encryption scheme of adjustable authentication is proposed by means of hardware algorithm platform,sign sequence number of application data packet and dynamic adjustable key counter.The algorithm can run smoothly on the network by adding small hardware components in exchange for the parallel computation of adjustable factor and encryption,which supports the application of resource-limited embedded devices.Experimental results show that this method can shorten the whole runtime of the system and improve the overall running efficiency.
