Abstract: Aiming at the securing hole of UMA-RFID protocol, a ultra-lightweight RFID mutual authentication protocol is proposed. Through improving the interaction of UMA-RFID, the identifier of tag can be avoidably leaked and the freshness of message for tag answering can be realized each time. XOR operation and shift operation are merely utilized in the proposed protocol, and the demand for the capacity of calculation and storage of tag are reduced. The analysis of security and performance shows that this protocol can efficiently resist spoofing attack, which is suitable for much lower-cost RFID system.

摘要： 针对UMA-RFID协议的安全漏洞，提出一个改进的超轻量级的RFID认证协议。通过修改UMA-RFID协议的交互方式，避免泄露标签标识符，保证读写器应答消息的新鲜性。该协议仅使用异或操作和移位操作，降低了对标签计算能力和存储能力的要求。分析结果表明，该协议可有效抵抗假冒攻击和重传攻击，适合于较低成本的RFID系统。
