【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;另一方面,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.更多还原

【Abstract】 Based on the public physically unclonable function(PPUF),an efficient RFID privacy-preserving authentication 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 unclonability 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.更多还原
