摘　　要：针对现有无线射频识别标签所有权转移应用中出现的后向隐私泄露、暴力破解等安全漏洞,设计一种改进的满足后向不可追踪的匿名RFID标签所有权转移算法。在满足轻量级标准下,使用二次剩余算法作为新、旧所有者之间的保护屏障改进算法漏洞,使新的算法满足后向不可追踪性等多种安全性;通过建立完整GNY逻辑安全框架,证明算法的合理性、完整性。通过安全性分析,证明该算法满足安全;通过性能分析,说明改进算法适用于无源标签的低成本性。In view of the security vulnerabilities such as backward privacy disclosure,violence cracking and so on in the existing RFID tag ownership transfer applications,an improved RFID label ownership transfer protocol satisfying backward and non-traceability is designed.Under the lightweight standard,it used the quadratic residue algorithm as the protection barrier between the new and the old owners,and made the new protocol meet a variety of security,such as non-traceability,and so on.A complete GNY logic security framework was established to prove the rationality and completeness of the protocol.Through the security analysis,it is proved that the improved protocol satisfies the security.The performance analysis shows that the improved protocol is applicable to the low cost of passive tags.
