摘　　要：针对传统式RFID系统无法满足当前移动式需求的问题,提出一种适用于移动式RFID系统的双向认证协议。该协议摒弃传统加密算法,引入创新型的异或交叉运算对消息进行加密;加密算法依据加密参数自身汉明重量值大小进行不同的运算,迫使攻击者无法获悉隐形参量信息,增加破解难度。从安全及性能角度对协议进行分析,该协议与其他此类型协议相比较,在具备高安全性的前提下,也满足低成本RFID系统的需求。Aiming at the problem that the traditional RFID system can’t meet the current mobile demand,a two-way authentication protocol for mobile RFID system is proposed.In this protocol,the traditional encryption algorithm is abandoned,and an innovative Exclusive or crossover is introduced to encrypt the message.The encryption algorithm performs different operations according to the Hamming weight value of the required encryption parameter itself,which forces the attacker to be unable to learn the hidden parameter information and increases the difficulty of cracking.The protocol is analyzed in terms of security and performance in this paper.Compared with other protocols of the same type,this protocol meets the needs of low-cost RFID system on the premise of high security.
