摘要
针对射频识别标签所有权转换过程的安全隐私问题,提出一种"先授权后更新"的所有权转换模式,并设计相应的实现协议。在密钥协商后,把标签的全部相关信息安全地转交给新的所有者。在相互认证的基础上,安全更新标签秘密,使得原所有者无法再对标签进行查询。该方案保证所有权转换过程中新用户的隐私安全。
Aiming at security and privacy threats during Radio Frequency Identification（RFID） tag ownership transfer, this paper proposes a ＂first delegation then update＂ ownership transfer mode. Corresponding protocols of the mode are also designed. All the information about the tag is transmitted to the new owner securely after a key negotiation. The tag＇s secret is updated securely after a mutual authentication, which makes the old owner can not query the tag any longer. The scheme ensures the privacy and security of the new owner in the ownership transfer.
