摘要: 为消除目前现有低成本无线射频识别(RFID)认证协议存在的各种安全隐患,解决认证协议所忽视的针对后端数据库的拒绝服务攻击问题,使用简单的逻辑运算以及读写器的屏蔽操作,以两个16位循环冗余校验(CRC)函数消息的级联作为标签与读写器相互认证因子,设计了一种新的基于低成本标签的RFID匿名双向认证协议,并对其进行了性能分析。分析结果表明,所提协议能够抵抗重放攻击和同步攻击,具备不可追踪性、真实性和服务的可用性,是一个比较安全、高效、实用的RFID低功耗安全认证方案。

Abstract: To remove hidden risks and solve neglected Denial-of-Service (DoS) attacks in the back-end database in current low-cost Radio Frequency Identification (RFID) authentication protocols, a new anonymous bidirectional RFID authentication protocol based on low-cost tags was proposed, and the performance analysis was conducted. According to the simple operative logic and shielded operation of reader, this scheme was designed by utilizing two cascading 16 bit Cyclic Redundancy Check (CRC) messages as mutual authentication factor between the label and the reader. The analytical results show the proposed protocol possesses untraceability, authenticity and usability and resists replaying attack and synchronization attack. Overall, it is a RFID low-power security authentication scheme of security, efficiency and practicality.
