| 摘 要： | USB设备通过主机的识别之后，与主机之间建立起一条USB传输信道，这是设备实现功能的基础。USB身份锁是网络身份认证系统中常用的信息载体，相比较常规USB设备，身份锁具有更高的安全性要求。文章给出一个基于厂商认证协议的身份锁强化识别方案，在实现USB设备标准配置的基础上，通过增加设备和驱动之间的可信身份认证，加强设备的识别处理。

| Abstract: | USB device functions only when a communication channel is set up between the USB device and its host after the completion of host-device recognition.A USB device can be used as a USB identity token.When it is used as an identity token in an network identity authentication system,a USB token requires more security than normal USB device.An improved USB token recognition scheme is proposed using a manufacturer authentication protocol.It upgrades the security level of the token identification by adding authentication procedures to the normal USB device recognition. |
