基于NTRU的RFID三方认证协议研究

摘要

针对目前提出的RFID协议存在认证安全问题以及较高时空复杂度，提出了一种采用高效NTRU加密的RFID三方认证通讯协议。建立对标签、阅读器和后台三方认证的通讯模型。结合实际存在的安全威胁，分析了所提出协议的安全性及性能。相比其他相关协议，在相互认证方面具有更高安全性和良好的性能表现。%Aiming at the present problems existing in security of RFID protocol and high spatial and temporal complexity, a new communication protocol which uses an efficient NTRU encryption for RFID tripartite certification is proposed. Based on the tags, readers and servers tripartite certified communication model is built. Combined with the actual security threats, safety and performance of the proposed protocol are discussed. Compared with other relevant protocols, the protocol has provided improved security in mutual authentication and good performance.
