一种能抵抗拒绝服务攻击的RFID安全认证协议

在分析现有一些RFID认证协议的基础上,采用流密码加密和密钥动态更新的方法设计了一种能抵抗拒绝服务攻击的RFID安全认证协议。对该协议的安全性和性能进行了分析,结果表明协议能够有效防止拒绝服务攻击、隐私攻击、窃听攻击、重传攻击,同时解决了RFID的隐私问题。

New defending RFID authentication protocol against DoS attacks

By analyzing some existing RFID authentication protocols, this paper proposed a new mutual authentication protocol, which was based on the use of symmetric encryption and dynamic update key to prevent the denial-of-service attack.Then discussed the security and performance of this protocol. The result shows that this protocol has provided good security for RFID system, and can defeat location privacy attack, relay attack,eavesdropping attack, denial-of-service attack, and solve problems of RFID security privacy.
