Implementation system for trusted execution environment of mobile terminal application program

Abstract

The invention discloses an implementation system for a trusted execution environment of a mobile terminal application program, which is characterized by comprising a mobile terminal equipment side and an application program developer side; the mobile terminal equipment side comprises a common world non-safe sensitive environment, a common world trusted execution environment and a safe world; the common world non-security sensitive environment comprises an untrusted operating system, a trusted execution environment management module and a non-security sensitive application program; the common world trusted execution environment comprises a security operation system, a system management module and a security sensitive application program; the secure world comprises a trusted operating system, an integrity verification module, a trusted application program and an EL3 security monitor; the EL3 security monitor comprises ARM trusted firmware, an interrupt management module, a page table management module, a system starting module, a system closing module, a peripheral access module and a resource adjustment module; and the application program developer side comprises an application program splitting module and a library generation module.

Description

technical field [0001] The invention relates to a system for realizing a trusted execution environment of a mobile terminal application program, and belongs to the technical field of mobile terminal device user privacy and data security. Background technique [0002] With the rapid development of mobile devices and mobile applications, mobile computing has significantly changed people's daily lives, making people's lives more and more convenient. However, the rapid development of the mobile terminal has made the precious value of user privacy and company confidential data more and more apparent, attracting many malicious attackers to steal user privacy or confidential data. Therefore, the security of mobile computing becomes more and more important. [0003] As the main force of mobile chips, ARM launched TrustZone, a trusted execution environment for the ARM platform, in 2003. A Trusted Execution Environment is a secure area in a processor that guarantees that code and da...

AI Technical Summary

Problems solved by technology

This feature can lower the use threshold of TrustZone to a certain extent, but it still faces the problem of limited resources and limited functions in the security world; in addition, this feature only appears in the ARM v8.4 standard, and has not yet released support The hardware of this feature cannot currently be used to solve the serious security problems faced by mobile applications

[0005] Therefore, currently TrustZone is not friendly enough to mobile applications, and mobile applications are eager to be protected at the trusted execution environment level, so a system for implementing a trusted execution environment for mobile applications is needed
