摘　　要：针对移动认证协议安全性不足和功能性不强的问题,提出一个改进的协议。改进的协议基于一种创新性的算法进行加密,即交叉移动运算对信息进行加密,加密算法将根据加密参数自身汉明重量值的不同而进行相对应的交叉操作及移动操作,增大攻击者破解难度;同时,交叉移动运算采用位运算方式实现,使得加密算法达到超轻量级的级别,降低系统整体计算量;为弥补原协议存在的不足,改进协议对每个信息加密后再传送,可抗攻击者假冒攻击。对改进协议进行安全和性能两个角度分析,改进协议不仅弥补了原协议存在的不足,且满足较高安全需求,同时适用于现有低计算量的移动RFID系统中。Aiming at the problem of insufficient security and weak functionality of the mobile authentication protocol,an improved protocol is proposed.This improved protocol encrypts the information based on an innovative algorithm,that is,the cross-movement operation.According to the different Hamming weight values of the encryption parameter,the encryption algorithm performs corresponding cross operation and movement operation,which increases the difficulty of cracking.Meanwhile,the cross-movement operation is implemented by the bit operation,which makes the encryption algorithm achieve ultra-lightweight level and reduces the overall calculation of the system.In order to repair the deficiencies of the original protocol,this improved protocol encrypts each message before sending it,which can resist counterfeit attacks.The security and performance analysis of the improved protocol shows that the improved protocol not only overcomes the shortcomings of the original protocol,but also meets the higher security requirements,and is applicable to the low-calculation mobile radio frequency identification(RFID)systems.
