摘　　要：针对无线射频识别(RFID)技术标签在生命周期内安全转移其所有权的问题,提出一个不依赖可信第三方参与转移的、基于Hash函数的RFID标签所有权转移协议。采用挑战响应机制,使用Status标志位来标识标签当前所有权归属。其中新旧所有者分别与目标标签共享不同的密钥,并与其传递通信数据来认证参与转移实体的身份,从而认证新所有者获得目标标签的所有权。分析结果表明,该协议满足标签所有权转移的安全需求,目标标签在执行协议后为新所有者所有,实现了所有权的排他转移,在安全性和效率方面较已有RFID标签转移协议有较大提高。Aiming at the problem of the tag＇s ownership safe transfer during its lifetime,an ownership transfer protocol for Radio Frequency Identification（RFID）is proposed,which is based on the Hash function without the Third Trust Party（TTP）. It adopts the challenge-response mechanism,and uses the Status flag to indicate the tag＇s owner. In this protocol,the previous owner and the new owner share different secret keys with the target tag respectively,with communication information transferred between them,and the entities in systems can be authenticated. After a serious of authentication,the new owner obtains the ownership of the target tag. Analysis result shows that the protocol can satisfy the proposed security requirements for tag ownership transfer. The target tag is owned by the previous owner,and only owned by the new owner after the protocol＇s execution. So it can make the tag＇s ownership transfer exclusively.Compared with the previous works,the protocol＇s performances on security and implementations are improved.
