基于PUF的开环RFID所有权转移协议

本文主要针对在供应链的交接过程中，标签在转移时的安全隐私和转移效率低的问题。为了针对低成本标签的安全与隐私问题，采用物理不可克隆函数（Physical Unclonable Function，PUF）和随机数等作为加密机制；为了抵御内部读写器攻击，使用伪随机数随时更新；采用PUF来保护标签的暴力攻击，将PUF和随机数结合实现标签的匿名和不可被追踪性；采用Rabin算法实现加密；采用Vaudenay模型来证明所有权转移的安全与隐私性。仿真结果表明，所有权转移时间降低，加快所有权转移的速度，提高供应链交接的效率。

Open-loop RFID ownership transfer protocol based on PUF

This paper mainly aims at the security and privacy issues and the low efficiency of transfer in the process of handover in the supply chain. In order to solve the security and privacy problems of low cost tag, Physical Unclonable Function(PUF) and random number are used as the encryption mechanism. In order to resist internal reader attacks, pseudo-random numbers are used to update at any time. PUF is adopted to protect the violent attacks of tags, and the combination of PUF and random numbers can realize the anonymity and untraceability of tags. Rabin algorithm is used to encrypt. Vaudenay model is used to prove the security and privacy of ownership transfer. Simulation results show that the time of ownership transfer decreases, the speed of ownership transfer is accelerated, and the efficiency of supply chain transfer is improved.
