为保证无线射频(RFID)标签的安全性，降低攻击行为的损失，提出一种改进的 RFID 身份认证协议。在标签受到异步攻击时，通过标签中写入的随机种子数，产生非对称密钥，经过与后台数据库预留密钥进行验证，使被攻击的标签恢复到同步状态，从而降低标签数据泄露的风险，保证 RFID 系统的数据安全性。

To ensure the security of RFID tags and reduce the loss by aggressive behavior,this paper presents an improved RFID authentication protocol.When the tag is asynchronously attacked,through the randomly written seed number,asymmetric keys is produced,and after the verification with the key pre-reserved in the backend database,the attacked tag is recovered to the synchronous state,thereby re-ducing the risk of tag data leakage and ensuring data security of RFID systems.
