摘要
针对射频识别(RFID)群组证明协议中的安全和隐私问题,重点分析Cho等提出的一种RFID群组证明协议中存在的交错攻击问题,在此基础上,提出一种改进的RFID群组证明协议。利用消息认证码和伪随机数生成器等加密技术,以及计算结构上的不对称性,保障协议的安全和隐私。安全分析结果表明,该协议与其它相关协议相比具有更强的安全性和更好的隐私保护。将该协议扩展为相对应的针对多个RFID标签的群组证明协议。
Aiming at the issues of security and privacy for RFID grouping proof protocol, the existing issue of interleaving attack of a kind of RFID yoking proof protocol proposed by Cho et al was analyzed emphatically. On this basis, an improved RFID yoking proof protocol was proposed. Encryption technologies were used such as message authentication code and pseudo random number generator, and asymmetry of calculating structure was adopted, to protect the security and privacy of the protocol. The analysis of security shows that the proposed protocol possesses better security performances and privacy protection. The proposed protocol was expanded into the corresponding grouping proof protocol for multiple RFID tags.
