基于自组合交叉位运算的超轻量移动认证协议

Ultra-lightweight mobile authentication protocol based on self-assembly crossover

针对无线射频识别(RFID)系统移动认证中存在的系统成本较高、无线通信不安全等问题,提出一种超轻量级移动RFID认证协议。给出自组合交叉位运算的定义,结合移位、异或运算加密秘密通信数据,使协议达到超轻量级别,降低系统成本;以完整三方认证过程为基础,利用随机数的新鲜性原则实现三方密钥更新机制,保证系统安全性。GNY逻辑形式化证明表明了该协议的有效可达性,安全性描述分析与性能对比统计验证了该协议具有高安全、低成本特性。

To solve the problems of high system cost and wireless communication insecurity in mobile radio frequency identification(RFID)system,an ultra-lightweight mobile RFID authentication protocol was proposed.Definition to explain the combination of self-assembly crossover operation was provided.Combined with the shift and XOR,communication data were encrypted,and the agreement reached ultra-lightweight level,reducing the cost of the system.On the basis of the three party authentication process,the key of the system was updated using the freshness of the random number,and the security of the wireless communication was guaranteed.The GNY logic formal proof was given to show the availability of the protocol.Through the security analysis and performance comparison,it is verified that the protocol has high security and low cost.
