针对RFID系统存在的安全隐患，提出基于多项式同余类的RFID安全协议。在伽罗瓦域基础上构建多项式同余类代数系统，在选定素数p和不可化约多项式情况下已知加密多项式求解密钥是容易实现的，而其逆过程是困难的。通信过程中阅读器生成伪随机数，密钥通过加密多项式传递给标签。对协议在RFID系统上的认证过程进行了详细描述。该协议使用对称密钥加密机制，采用一次一密分组加密方法，具有高安全性。

This paper proposes a polynomial congruence class-based RFID security protocol aiming at the security risk in RFID system.An algebra system,which consists of polynomial congruence class,has been established based on Galois field.In the context of selected prime number p and irreducible polynomials,it is known that to implement the encryption on polynomial solution key is easy.However,its inverse process proves to be difficult.During the process of communication,reader generates a random number and the key is passed to the label by encrypting polynomial.In this paper,we describe the protocol verification process in RFID system in detail.The protocol has high security by using a symmetric key encryption mechanism and adopting one-time-pad method.
