Problems solved by technology

The client application does not authenticate the trusted application, which may easily cause the client application to be unable to identify the trusted application that has been forged or tampered with, or the trusted application that has been misused, allowing hackers to attack business applications by forging or tampering with trusted applications
The trusted application does not authenticate the client application call, which may easily cause the trusted application to be accessed by the illegal client application, resulting in the leakage and theft of data stored in the trusted execution environment

Abstract

The invention discloses an authentication method and system in a trust execution environment, and relates to the technical field of mobile terminals. The authentication method comprises the following steps: a system communication drive acquires feature information of a client application CA, and sends a trust application TA to the CA to perform the identity authentication; and / or the system communication drive acquires the feature information of the TA, and sends the CA to the TA to perform the identity authentication. The identity authentication between the client application and the trust application is accomplished through the cooperation of the system communication drive, and the security is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an authentication method and system in a trusted execution environment. Background technique [0002] With the rapid development of the mobile Internet, the types and quantities of mobile applications are increasing. The security of business processed and stored data in mobile terminals is also increasingly threatened, especially for industrial applications with high security requirements such as payment, office work, and copyright protection. However, the design of the operating system of the smart terminal focuses on functionality, is open, and is large and complex with many system loopholes, making malicious applications appear continuously and threatening the user's data security. [0003] In order to meet the high security requirements of mobile applications, industry research has proposed a TEE (Trusted Execution Environment, Trusted Execution Environment) solutio...
