RFID技术可以很方便地自动识别目标对象并获取相关信息，但因RFID利用射频信号获取数据的过程无需要接触且不通知持有者而导致安全及隐私问题。针对这一状况学者提出诸多方法以应对，其中基于密码技术的协议因更具备灵活性而受到重视。为了提供更好的安全性，需要使用高强度的密码算法，而这通常会导致标签成本的增加。为此，笔者提出一个使用口令提升RFID识别协议安全性的新方法，口令作为识别的必须数据以抵抗非授权的恶意读取来提升识别过程的安全性，并且在读写器端接受口令，不增加标签制作成本。

By using of RFID （Radio Frequency Ide get its information conveniently and automaticall ntification） technology, we can identify an object and y, but it causes security and privacy problem for its exchange information without contacting and without notifying the tag owner via radio waves. In response to this situation, scholars proposed many authentication protocols. The cryptographic techniques based schemes are attended due to its flexibilities. For promoting the security guarantee, heavyweight cryptographic techniques can be employed, but it cost and it not fit the requirement of the RFID coats. In order to solve the problem, a method for RFID authentication protocol by using of simple password is given. The password is involved in the authentication process, and it is indispensable. This can resist the illegal reading of the RFID tags and promote the security. The input interface is on the RFID reader side, and it is not adding the tags burden.
