摘要
由于标签强大的追踪能力,无线射频识别(RFID,Radio Frequency Identification)技术越来越多地被应用到与安全相关的各个领域,从而对安全功能的要求也随之提高。针对轻量级RFID标签在使用中的安全问题,对现有的认证协议潜在的危险进行了深入的分析,在此基础上提出了一种基于流密码的认证协议。在此安全协议中,标签和阅读器之间进行多次的双向认证,可以确保通信双方的合法性;并充分考虑了在实际应用中,标签的低成本要求。
Owing to the labels＇ powerful traceability,Radio Frequency Identification（RFID） technology is increasingly applied to security-related fields,thus enhancing the security functional requirements.For safety of the Lightweight RFID tags in use,the potential dangers of the existing authentication protocols are analyzed in detail,and based on this,a stream cipher-based password authentication protocol is proposed,in which multi-time two-way authentications between the tags and readers are implemented,thus to ensure the legality of the communicating parties.Meanwhile,the low-cost labeling requirements in practical applications are also comprehensively considered.
