An Authentication Protocol Based on Key Array for RFID
-
摘要: 随着RFID技术的发展和广泛应用,安全认证协议的设计与完善对于保护信息安全和用户隐私变得更加重要。该文针对现有安全认证协议中常常忽略的来自系统内部合法阅读器之间的伪造和篡改问题,提出一种新的基于密钥阵列的安全认证协议。它通过增加密钥更新标记,有效地解决了标签和数据库之间的同步更新问题。新协议在维持一定复杂度和标签成本的基础上,可抵抗包括重传、跟踪、阻断和篡改等多种攻击手段,尤其针对来自系统内的安全威胁,具有较高的安全性和实用性。Abstract: As RFID becomes more and more popular, it is imperative to design authentication protocols to resist all possible attacks and threats. In order to overcome counterfeits of readers, a new authentication protocol is proposed based on key array. The new protocol can deal with the synchronization of key update by adding flags of key update. It can resist several possible attacks, including reply, tracking, blocking, proofing and inner attacks. Compared with other authentication protocols, the new protocol can improve the security of RFID systems effectively and does not increase the complexity of protocol.
