摘　　要：安全认证协议是解决RFID系统安全威胁的有效手段,针对一些基于Hash链的认证协议存在的安全和效率问题,提出了一种基于Hash链和非对称密钥的改进协议。将非对称密钥应用到标签和后台数据库之间的数据加密可以提高系统的安全性;后台数据库用解密后的ID值建立动态索引,提高了后台数据库检索效率。与现有协议进行对比分析,结果表明该协议可以抵抗常见攻击,能够有效提高后台数据库的检索效率和标签认证效率。Security authentication protocol is an effective method to solve the security threats of RFID system. Aiming at some problems existing in the safety and efficiency of authentication protocols,we proposed an improved asymmetric key protocol based on Hash chain. The security of the system can be improved by applying an asymmetric key in data encryption between a tag and a backend database. The dynamic index is created by decrypted ID of the backend database,which improves the retrieval efficiency of the database. Compared with the existing protocols,the improved asymmetric key protocol can resist many common attacks and improve the efficiency in the background database retrieval and tag authentication.
