摘要
无线射频识别(RFID)系统的双向认证机制可以有效地保护标签的机密性。对超轻量级RFID认证协议(ULAP)的安全性进行分析,结果表明,通过侦听多轮(预期值为10)阅读器和标签认证消息,就能推导出标签的全部秘密信息,因此ULAP协议不能抵抗被动攻击。
Mutual authentication mechanisms can be used in Radio Frequency Identification(RFID) systems to preserve the confidentiality of the RFID tags. In this paper, a passive attack is presented on a mutual RFID authentication protocol--ULAP(Ultra Light-weight Authentication Protocol), which is designed to resist passive attack. The attack shows that after eavesdropping a few numbers of round communication(expected number is 10), all the secret of the tag can be deduced. Therefore, ULAP can not resist passive attack.
