摘要： 无线信号的广播传输、资源受限等特点使RFID 技术存在潜在安全隐患。为此，将公钥加密算法与对称密钥加密算法有机地结合，提出一种新的RFID安全认证协议，该协议解决了RFID系统中的信息泄露、重传攻击、位置追踪、假冒攻击、去同步化等安全与隐私问题。对该协议的安全性和性能进行比较分析，结果表明该协议可以为RFID系统提供较好的安全性，适合于RFID系统的应用。

Abstract: Wireless transmission, broadcast of signals, resource-constraint, etc. bring some potential risks. This paper proposes a new mutual authentication protocol for RFID system. The protocol combines commendably public key encryption and symmetric cryptosystem for challenge-response based authentication. It can prevent many security problems including information leakage, replay attack, location tracing, spoofing attack, etc. The paper compares and analyzes the security and performance of the protocol, result shows that the protocol has more security for RFID system, it can be applied to RFID system.

Key words: authentication protocol, Hash function, tag, reader, security
