摘要： In one embodiment, a system wake-up vector points to a native OS wake-up routine. As the native OS awakens from sleep it passes the wake-up message to the appropriate device drivers. A hardware device whose security context to be restored hooks the appropriate driver in order to intercept and handle the wake-up message. In a second embodiment, a system wake-up vector is redirected to a device specific S3 wake-up subroutine that handles a resume from S3 prior to allowing the call of the native OS wake-up vector. This S3 wake-up subroutine challenges a user for authentication credentials or retrieves them from a hardware device. The supplied credentials are used directly or to decrypt an unlock key from an encrypted key in memory. The unlock key would then be used to unlock the hardware device or fed to the native OS for processing by a device driver capable of unlocking the hardware device.
摘要翻译：在一个实施例中，系统唤醒向量指向本地OS唤醒例程。由于本地操作系统从睡眠唤醒，将唤醒消息传递给相应的设备驱动程序。要恢复的安全上下文的硬件设备会挂起相应的驱动程序，以拦截和处理唤醒消息。在第二实施例中，系统唤醒向量被重定向到设备特定的S3唤醒子例程，其在允许本机OS唤醒向量的呼叫之前处理来自S3的恢复。这个S3唤醒子程序向用户挑战身份验证凭据或从硬件设备检索它们。提供的凭据直接使用或从存储器中的加密密钥解密解锁密钥。然后解锁密钥将用于解锁硬件设备或馈送到本机OS，以便能够解锁硬件设备的设备驱动程序进行处理。
