一种新的轻量级RFID双向认证协议

New Mutual Authentication for Lightweight RFID Protocols

RFID技术是一种广泛应用于各种物体识别和跟踪的自动识别技术,它适用于多个领域。然而,设计出一个安全的轻量级的RFID认证协议是一项具有挑战性的任务。最近Kulseng等人提出了一种轻量级RFID认证协议,该协议采用物理不可克隆技术和线性反馈移位寄存器来实现,非常适合轻量级操作。分析发现,该协议存在几个严重的安全问题。在分析上述协议的基础上,提出了一种新的轻量级RFID双向认证协议。分析表明,新协议在保持轻量级操作的同时,具有更好的安全性和保密性。

Radio frequency identification（RFID）technology is an automated identification technology which is widely used to identify and track all kind of objects.It is well suitable for many fields.However,it is a challenging task to design an authentication protocol because of the limited resource of lightweight RFID tags.Recently,a lightweight RFID authentication protocol of RFID tags were presented by Kulseng et al.This protocol uses physically unclonable functions（PUFs）and linear feedback shift registers（LFSRs）which are well known for lightweight operations.Unfortunately,their protocols face several serious security issues.In this paper,based on PUFs and LFSRs,we suggested a new mutual authentication for low-cost RFID Systems.Security analysis shows that our protocol owns better security and privacy.
