摘　　要：针对无线射频识别系统存在的初始密钥易泄露的安全问题,提出了一种基于标签部分ID的RFID密钥无线生成算法。在标签与读写器认证之前,通过标签部分ID与读写器生成的随机数进行异或运算生成共享密钥。安全性分析表明,该算法能够有效地抵抗重放攻击、中间人攻击和去同步化攻击等主动攻击及被动攻击,具有安全性高、成本低的优点。Aiming at the security problem that the initial key is easy to leak in the wireless radio frequency identification system, a RFID key wireless generation algorithm based on tag part ID was proposed. Before the tag and reader authen- tication, the sharing key is generated by the part of label ID and the random number reader generated XOR. Security a- nalysis shows that the proposed algorithm can effectively resist replay attacks, man-in-the-middle attacks, desynchroni- zation attacks and other active attacks, as well as passive attacks, with high security and low cost advantages.
