一种RFID系统反跟踪安全通信协议

AN ANTI-TRACING SECURITY COMMUNICATION PROTOCOL ADAPTED TO RFID SYSTEM

典型RFID标签在计算能力和通信、存储等方面的能力受到严格限制,如何保证RFID系统的安全性对传统安全问题提出了许多挑战。提出一种不可追踪的RFID通信协议UNTRACE,在标签端只需要计算一个密钥hash函数,以最小的代价实现标签和阅读器之间的交互,同时后端服务器的计算代价也很低。通用的协议分析方法证明此协议的性能与已经提出的协议相当,而计算代价较低。

The computing ability, communication ability and storing ability of typical RFID tag and reader are strictly limited, this puts for-ward challenges to traditional security system in bow to keep RFID system secure. To make up the shortcomings of existing methods, an antitracing RFID communication protocol, called UNTEACE,is proposed in this paper, which only computes one key Hash function for tags, and implements the interaction between tags and readers with least cost. At the same time,the computational cost of backend sever is low too. Universal analyses method of protocol proves that the proposed protocol has equal performance to existing famous anti-tracing protocols but has lower computation cost.
