Abstract: RFID tags in the use process will involve the transfer of ownership, for this reason, this paper designs a security requirement to meet the ownership transfer protocol. The protocol does not depend on the trusted third party and can reduce the number of communication entities. The new owner of the tag introduces the counter count to solve the desynchronization attack problem. The security of the designed protocol is analyzed, and the designed protocol can meet the security requirements for the transfer of ownership of labels.

摘要： RFID标签在其使用过程中会涉及到所有权转移的问题，针对于此，设计出一种满足安全需求的所有权转移协议。设计出的协议不依赖可信第三方，能够减少通信实体数；采用挑战响应机制，标签的新所有者端引入计数器[count]，根据[count]的值进行相对应的操作，解决去同步化攻击问题，设计出的协议能够满足标签所有权转移需要的安全要求。
