将变伪码（VP）应用于射频识别（RFID）认证协议的设计，在多个方面优于现有的方法。但是，这种方法容易受到众所周知的拒绝服务（DOS）攻击。在本文中，我们研究了基于VP的RFID认证协议的去同步问题，并提出了有效的解决方案，以消除这些弱点。我们将证明所提出的解决方案确实提高了这些协议的安全性，而且，这些解决方案需要O（1）的计算成本来识别标签和O（1）的标签上的密钥空间。这些优异的性能使它们对许多RFID应用非常有吸引力。
Applying Varying Pseudonym (VP) to design of Radio Frequency Identification (RFID) authentication protocol outperforms the other existing approaches in several respects. However, this approach is prone to the well-known denial-of-service (DOS) attack. In this paper, we examine the de-synchronization problems of VP-based RFID authentication protocols, and propose effective solutions to eliminate such weaknesses. We shall show that the proposed solutions indeed improve the security for these protocols, and moreover, these solutions require O(1) computational cost for identifying a tag and O(1) key space on the tag. These excellent performances make them very attractive to many RFID applications.
