摘要
随着射频识别(RFID)技术的发展和广泛应用,RFID系统的安全性成为了研究的热点,但是由于标签有限的计算能力和存储能力,安全协议的设计成为了保证RFID系统安全的关键。文章对SYK协议的安全性进行了分析,针对其存在的多个安全漏洞进行改进,提出了一种改进型的RFID相互认证协议。安全性能分析表明,改进后的协议通过标签和数据库的信息同步更新和散列函数加密,解决了SYK协议的安全隐私问题,满足基本的安全性能,可以抵制跟踪、去同步、重传等多种攻击,提高了RFID系统的安全性。
With the radio frequency identification （RFID） technology developed and widely used, the safety of the RFID system becomes the focus of research, but the design of security protocols becomes the key to ensure the safety of RFID system because of the limited computing and storage capacity of the tag. In this paper, analyzing the safety performance and improving the security multi-vulnerabilities existed in the SYK protocol, an improved RFID mutual authentication protocol is proposed. Safety performance analysis shows that the proposed protocol solves the privacy problem of the SYK protocol through the synchronous updating of the information and hash function of encryption,meeting the basic satety requirements and overcoming various attacks, such as a-acking de-synchronization and replay at- tack. The security of the RFID system is strengthened.
