> 中文摘要: 基于对称密码体系的RFID隐私保护认证协议的构造是学术界和工业界研究的热点问题.具有完整性隐私保护协议的效率不够高效,需要对系统中所有的标签进行穷尽搜索,难以应用于物联网海量终端的环境.给出了一种高效的RFID隐私保护认证协议的构造方法.构造的协议采用了单比特输出的伪随机函数,将协议的认证过程分解为多个步骤,与传统的基于对称密码体系的RFID认证协议相比,构造的协议显著提高了读写器对标签的搜索效率.构造的协议具有隐私性,并且计算开销小,读写器端对标签的搜索效率高,能够很好地应用于海量终端的物联网环境.

Abstract:Privacy-preserving RFID authentication protocols based on symmetric-key cryptography technology have increasingly become popular. However, current RFID authentication protocols are inefficient due to the requirement of full search for all the RFID tags in the systems. In this paper, a new efficient method is proposed to construct highly effective privacy preserving RFID protocols. Based on pseudorandom functions with single output bit, this protocol can significantly improve the performance of tag searching process. Moreover, the protocol satisfies anonymity, authenticity, and efficiency requirements in the large-scale systems.
