摘　　要：针对传统RFID系统的认证协议无法使用在移动RFID系统中的问题,先分析已有的认证协议,指出其不足,并在此基础之上,设计一种能够抵抗攻击者假冒攻击的移动RFID双向认证协议。采用密文方式进行信息传输,能够保证隐私信息的安全性;摒弃计算量较大的哈希函数加密,采用交叉位运算对信息进行加密,能够较大幅度降低通信实体的计算量;为确保信息的安全性,每个步骤进行前,先对发送消息的通信实体进行认证,认证未通过,协议马上结束。安全性分析表明,该协议能够抵抗攻击者发起的假冒攻击等攻击方式;性能分析表明,该协议在标签端的计算量要优于其他协议。The authentication protocol of traditional RFID system cannot be used in mobile RFID system.In order to solve the problem,this paper analyzes the existing authentication protocols,points out the shortcomings,and designs a mobile RFID bidirectional authentication protocol,which can resist attackers counterfeiting attacks.It used cipher text to transmit information,which could ensure the security of privacy information.By using cross bit operation to encrypt information instead of hashing function encryption,the computation of communication entity could be greatly reduced.In order to ensure the security of information,each step was preceded by authentication of the communicating entity sending the message.If the authentication failed,the agreement would be terminated immediately.The security analysis of the protocol shows that it can resist attacks such as counterfeit attacks initiated by attackers.The performance analysis of the protocol shows that its computation on the label side is better than that of other protocols.
