摘要
对低成本RFID(Radio Frequency Identification)系统存在的安全性问题进行了分析,并提出了一种新的安全认证协议。该协议使用散列函数、异或运算及移位运算等常见算法,既解决了安全问题又降低了标签要求。通过在服务器上保存每个标签的新、旧标识,有效地解决了服务器和标签的同步问题,同时能抵御窃听、重放、跟踪、阻断、模拟等多种攻击。通过性能分析,该协议比常用的Duc、CC协议在标签的存储空间和计算能力等方面要求更低,适合低成本标签使用。
This paper analysed the security problem existed in low-cost RFID system, and presented a new security authorization protocol. This protocol uses common algorithms, such as hash function, XOR computation and shift operation, while resolves the security problem, it reduces the requirements of tags as well. It effectively tackles the synchronous problem between the server and tags by storing new and old identifiers of every tag in the server. At the same time it can resist eavesdropping, replay, track, block, simulation and other attacks. Through the performances analysis, this protocol has less memory and computing ability requirement compared with the common protocols such as Duc and CC, and is suitable for the low-cost tag' s environment.
