文摘不经意传输(OT,oblivious transfer)协议是密码学中的一个基本协议。基于物理不可克隆函数(PUF,physical unclonable function)给出物理不可克隆函数系统(PUFS,physical unclonable function system)的概念,并在此基础上提出一个新的不经意传输协议(POT,PUFS based OT),最后在通用可组合(UC,universal composition)框架内给出POT协议抵抗静态敌手的安全性证明。相比于传统基于公钥加密的OT方案,POT协议不使用任何可计算的假设,而是基于PUFS的安全属性实现,因此在很大程度上减小了计算和通信开销。
