基于Hash函数的RFID协议改进方案

Improvement Plan of RFID Protocols Based on Hash Function

近年来,随着RFID的广泛应用,它的安全问题引起了人们的重视.目前常用的RFID安全协议都存在着各种各样的缺陷.本文在分析了常用RFID安全协议的缺陷的基础上,提出了一种新的改进方案.新方案中通过在后端数据库和标签之间增加计数值的办法减少后端数据库进行Hash运算的次数,旨在从整体上提高系统的效率.

In recent years, with a wide range of RFID applications, the security issues of RFID raise the attention of people. At the present, the staple security protocols about RFID have all kinds of defect. In this paper, I propose a new improvement protocol based on analysis of several commonly used RFID security protocols. The new plan aims to improve overall system efficiency by setting count values between back-end database and tags to reduce the numbers of database on making Hash operation. And the new improvement plan improves the efficiency of the system.
