一种全新的RFID标签所有权转移协议

RFID标签在所有权转移过程中面临安全和隐私泄露的风险。针对这一问题,提出了一种带有转移开关并基于Hash函数的新型标签所有权转移协议。原所有者和新所有者分别拥有不同的通信密钥,前者的密钥用于原所有者与标签之间的认证,后者的密钥用于标签与新所有者之间的所有权转移。由于存在转移开关(Ownership Transfer Switch,OTS),因此可以通过对OTS的设置来实现抵抗去同步化攻击。对该协议的安全性分析结果表明,该协议能够满足标签所有权转移的安全需要,并能抵抗常见的主被动攻击,使标签的所有权实现完全转移。最后对协议进行了性能分析,结果表明所提协议在效率性能方面比已有的RFID标签所有权转移协议有明显提高。

New Ownership Transfer Protocol of RFID Tag

There exists risk of security and privacy disclosure in the process of ownership transfer of RFID tag.Thus a new tag ownership transfer protocol with transfer switch based on Hash function was proposed .The original owner and the new owner have different communication keys respectively,the former key is used for authentication between the original owner and the tag while the latter key is for ownership transfer between the tag and the new owner.Because of the transfer switch,namely OTS,it is possible to implement OTS configuration to resist desynchronization attack through OTS configuration.The safety analysis of the protocol shows that the protocol can meet the safety requirements of tag ownership transfer and resist common active and passive attack,thus achieving complete transfer of tag ownership.Finally,the performance of protocol was analyzed and the results show that efficiency performance of proposed protocol is significantly improved compared with existing ownership transfer protocol of RFID tag.
