Credible device with active control function and authentication method thereof

Abstract

The invention discloses a credible device with an active control function and an authentication method thereof, relating to the field of information security. A credible platform control module with the active control function and a hardware device are connected to a credible platform of the credible device with the active control function, wherein the hardware device are separated into a credible hardware device and an incredible hardware device by the credible platform control module through the active control function, and the credible platform control module is internally provided with hardware units such as an active measurement engine, a control judgment engine, a work mode customizing engine, a credible control policy configuration engine and the like to realize active check on theworking condition configuration information of the hardware device, control policy configuration information, a firmware code and the working condition of a circuit. Mutual binding between the credible platform and the credible hardware is realized through combing the credible platform control module and a credible pipeline technology, the binding process of the credible platform control module and the credible hardware is completely transparent to an operating system and an application program, and the operating system cannot bypass or intervene the process of binding the credible hardware by the credible platform.

Description

technical field [0001] The invention relates to the field of information security, in particular to a trusted device with an active control function and an authentication method thereof. Background technique [0002] With the continuous deepening of research on trusted computing technology, the functional requirements of trusted computing specifications for trusted chips are also increasing. From the earliest TCG1.1 version to the current 1.2 version, from the application of computer terminals to servers, embedded devices, virtual machines, networks, etc., it can be said that trusted chips (trusted chips defined by TCG are called trusted chips) Platform module.) The functional requirements are constantly improving, and the design complexity is constantly increasing, which in turn also causes the hardware scale and internal firmware scale of the trusted chip to continuously increase. [0003] In the field of computer terminals, the existing trusted computing specifications d...
