摘要
随着射频识别(RFID)技术的广泛应用,隐私安全问题引起了人们的极大关注。首先从安全性和实用性方面讨论了现有的RFID安全协议存在的不足,然后对一种基于动态密钥的低成本RFID标签安全方案进行了分析,较好地解决了在认证协议中容易出现的数据不同步和重传攻击问题。
With the wide application of RFID technology, security issues have become the focus of public. This paper reviews the existing RFID system security protocols and discusses their deficiency in practicability and security. A low - cost RFID tag security scheme based on dynamic - key is studied and then the issues on the key asymmetry and replay attacks in the security protocols are effectively solved.
