一种具备原所有者无关性的无线射频识别标签所有权转换协议

针对标签所有权转换过程中的信息安全问题,提出了一种具备原所有者无关性的标签所有权转换协议。协议中主要包含原所有者、新所有者、标签和可信第三方四个通信实体。采用GNY逻辑对该协议的安全性进行了分析,结果表明该协议能够将原所有者对标签的所有权转交给新所有者;并能抵御跟踪攻击、重放攻击、中间人攻击和去同步化攻击,保护标签信息的前向安全和后向安全,提供原所有者无关性。对该协议进行了仿真实现,获取了标签计算耗时等数据。经过与其他协议的数据进行对比,该协议中标签的计算耗时较短,适用于低成本标签。

RFID Tag Ownership Transfer Protocol with Independence of Old Owner

An ownership transfer protocol of RFID tag with independence of old owner was proposed to protect the information security in the procedure of ownership transfer. It contains old owner, new owner, tag and trusted third party in the protocol. The protocol was analyzed by using GNY logic. The result indicates old owner transfers the ownership of tag to new owner. The protocol resists tracking attack, replay attack, man-in-the-middle attack and desynchronization attack. It protects forward security and backward security and provides the independence of old owner. We implemented and simulated the protocol and obtained computation time cost by tag. The data shows the protocol is suitable for low-cost tag because it is shorter compared with other protocols.
