Abstract

The invention provides an identity authentication method and device based on trusted computing. The method comprises the following steps: binding a TCM (Trusted Cryptography Module) in a computer system with a USBKey (Universal Serial Bus) in advance, and storing the reference value of each component in the computer system into the USBKey; when a login request of a target USBKey is obtained, judging whether the target USBKey is bound with the TCM in the computer system, and comparing the metric value of each component with a corresponding reference value stored in the USBKey to realize the first authentication of the target USBKey; and when the metric values of all components are the same with the reference value, authenticating the identity information of the target USBKey, and responding to the login request of the target USBKey according to an identity information authentication result to realize the secondary authentication of the target USBkey. Through the dual authentication of the target USBKey, data in the computer system can be guaranteed to be safe and trustable.

Description

technical field [0001] The invention relates to the field of computers, in particular to an identity authentication method and device based on trusted computing. Background technique [0002] Under the prospect of the country's strengthening of localization and substitution, domestic firmware and domestic operating systems have gradually developed and grown. Trusted computing technology, as a new type of computer information security technology, fully exerts its security and trustworthy functions under the localization platform, and provides basic support for the establishment of an information security support platform in terms of trusted authentication, trusted measurement, and trusted storage. . [0003] At present, trusted computing technology uses the internal algorithm of TCM (TrustedCryptographyModule, Trusted Cryptography Module) to measure the trustworthiness of each component in the computer system startup process step by step to determine whether the computer sys...
