中文摘要：

基于PPUF技术，设计了一个具有隐私保护功能的RFID认证协议RPAP．在协议RPAP中，仅要求标签配置一个PPUF函数，而不需要具备其他的计算能力，因此其标签的生产成本低；男一方面，PPUF函数的不可预测性和不可克隆性保证了RPAP协议具有强隐私性：证明了它能抵抗包括破解攻击在内的各种隐私安全攻击；同时PPUF函数的可仿真性保证了协议RPAP具有高效性和良好的可扩展性．

英文摘要：

Based on the public physically unclonable function （PPUF）, an efficient RFID privacy- preserving au- thentication protocol （RPAP） is presented. RPAP is low cost as no extra computational ability other than a PPUF is required for each tag. Furthermore, RPAP has been proven to be strongly private due to the unpredictability and unelonability of PPUF： it can be resistant to almost all kinds of privacy related attacks such as corruption attacks. Finally, the protocol of RPAP is efficient and scalable thanks to the simulatability of PPUF.
