低成本RFID的应用将越来越广泛,系统的安全问题已引起业界极大关注。由于低成本RFID标签的资源非常有限,难以采用比较成熟的复杂密码机制来实现Tag与读写器之间的通信安全。本文探讨了低成本RFID系统的安全隐患和安全需求,分析了已有的可用于低成本RFID的安全认证协议存在的缺陷,并提出了设计低成本RFID安全认证协议的建议。
The application of low-cost RFID will be more and more widespread, and the security of the system has caused great concern in the industry. Due to the limited resources of low-cost RFID tags, it is difficult to adopt the more sophisticated and complicated cryptographic mechanism to realize the communication between Tag and reader. This article explores the security risks and security requirements of low-cost RFID systems. It analyzes the shortcomings of the existing security authentication protocols that can be used for low-cost RFID and proposes the proposal of designing a low-cost RFID security authentication protocol.
