摘要
RFID(Radio Frequency IDentification)系统射频标签结构简单,且与阅读器间采用无线方式传输数据,易产生隐私泄露和受到安全攻击。针对该问题,文中提出通过双向轻权认证协议来保护RFID系统的安全性和隐私。该协议通过随机化标签的秘密信息再哈希的方法生成会话消息,标签与阅读器间采用二次相互认证,提升了协议的安全性。该协议通过哈希运算确保认证过程中会话信息的保密传输和完整性,通过对标签端每次发出会话消息的随机化确保了消息的新鲜性,系统秘密信息的更新确保协议满足前向安全性。RFID认证协议不仅能抵抗窃听、追踪、重放、去同步化等攻击,还能满足RFID系统的安全性和隐私保护需要。
In view of the problems of privacy leakage and security attack in RFID(Radio Frequency IDentification)system due to the simple structure of radio frequency tag and the wireless transmission of data between reader and RFID system,this study proposes to protect the security and privacy of RFID system through two-way lightweight authentication protocol.The protocol generates session messages by randomizing the secret information of tags and then Hashing them,and adopts secondary mutual authentication between tags and readers,which improves the security of the protocol.The protocol ensures the confidential transmission and integrity of session information in the authentication process through Hash operation.The randomization of each session message sent by the tag side ensures the freshness of the message,and the update of the system secret information ensures the forward security of the protocol.RFID authentication protocol can not only resist attacks such as eavesdropping,tracking,replay,and de-synchronization,but also meet the security and privacy protection needs of RFID systems.
