一种基于Key值更新的RFID安全协议设计

在一些经典的RFID安全协议基础上,提出了新的安全认证协议,能够防止假冒攻击、重放攻击、标签跟踪、前向安全性等,降低标签的硬件成本,缩短后台数据库的查询时间,减少数据库与标签之间的通信量,从而有效地增强了RFID系统的安全性。并且文章通过建立协议的理想化模型,运用BAN逻辑对协议进行了形式化分析,从理论上给予协议安全性证明。

RFID Secure Protocol Based on Key Value Renewal

In this paper, based on some classical RFID security protocol, a new protocol based on key value renewal is proposed. The new protocol canprevent RFID system from spoofing attack, replay attack, tracking as well as the problem of desynchomization and provide forward security. To thesystem performance, the protocol can reduce the hardware cost of tags, query time in backend database and the communication between each other.Consequently, the protocol effectively enhanced the security of RFID systems. Also thi...
