摘　　要：低成本RFID标签与读卡器间的相互认证或安全通信都依赖于通信双方预先共享的密钥,而攻击者可以通过物理攻击等手段获得该密钥.利用PUF电路的物理不可克隆特性,提出两个基于PUF的密钥协商协议,从中通信双方可以产生相同的随机密钥,供后续的认证或安全通信使用.分析结果表明,该协议可以有效抵抗物理、重放、假冒、中间人、离线猜测及在线猜测攻击,同时提供前向安全性和后向安全性.The secure mutual authentication or secure communication between the low-cost RFID tags and the card readers depends on a secret key shared by the two parties, which can be gained directly by a power attacker by means of physical attacks. Taking advantage of the physical unclonable feature of PUF circuits, two secure key exchange protocols are presented in this paper, such that the two parties can generate a same random key which can be used to secure the following authentication or communication. Security analysis shows that these two protocols can resist physical attack, reply attack, counterfeit attack, man-in-the-middle-attack, offline guessing attack and online guessing attack, and also can provide forward security and backward security.
