Abstract

The invention discloses a method for identity verification of a digital certificate based on a TEE (Trusted Execution Environment). The method comprises pre-configuration of a digital certificate system through a terminal, a digital certificate signature process and a digital certificate signature verification process. The method is characterized in that the terminal is provided with the TEE; the digital certificate signature process is carried out on the terminal and is used for utilizing a private key of the digital certificate to sign for a user request; the digital certificate signature verification process is used for authenticating identity of a requested user, and the authentication method comprises verification of validity and effectiveness of the digital certificate and integrity and correctness of the signature, wherein the digital certificate signature process is carried out under the TEE; the sensitive information, such as a user key, identity information, biological characteristic information and password information, is stored through a secure storage module, so that the problems that the signature process is carried out in REE and the sensitive information of the user is stored under the REE environment to cause privacy disclosure and stolen hidden danger of property in the prior art are avoided.

Description

technical field [0001] This application relates to the field of information technology, in particular, to a TEE-based digital certificate identity verification method and system. Background technique [0002] PKI is the abbreviation of PublicKeyInfrastructure, that is, public key infrastructure. It is a system or platform that provides asymmetric encryption and decryption and digital signature verification services. The purpose is to manage keys and digital certificates.
