摘要
针对射频识别(RFID)系统中存在的标签数据机密、安全等问题,研究Hash函数相关协议与对称密钥机制的优缺点,提出一种基于Hash函数与状态锁定的安全认证协议.该协议采用单向Hash函数与对称加密方法,结合后台数据库与标签状态的锁定设置,并在认证结束后及时更新ID和密钥值,有效处理RFID认证阶段的安全风险问题.通过安全性分析表明,该协议既保证了标签的匿名性、完整性、机密性,又抵御了攻击者假冒、重传、去同步攻击,能较好地完成RFID系统中阅读器与标签的相互认证.
For the issues of data confidentiality and security of tags existed in radio frequency identification （ RFID） system, the pros and cons of protocols related to Hash function and symmetric key mechanism was studied , and a kind of security authentication protocol based on Hash and state lock was proposed .The protocol uses Hash function and symmetric en-cryption method, combines with the setting of state lock in back -end database and tags , updates the values of ID and key after the authentication , and effectively deals with security risks in RFID authentication stage .The analysis of security showed that the protocol not only ensured the tags ’ anonymity , integrity and confidentiality , but also resisted the attacks of at-tackers’ fake, retransmission and desynchronization .It can be better to complete each other authentication of reader and tags in RFID systems .
