Digital wallet security framework system based on security unit and trusted execution environment

Abstract

The invention provides a digital wallet security framework system based on a security unit and a trusted execution environment. The security unit and the trusted execution environment are combined to construct the security framework system suitable for a mobile terminal digital currency wallet. Hardware of the mobile terminal comprises a security unit and a mobile terminal central processing unit supporting the ARM TrustZone technology. In the digital currency wallet security framework system, a security execution environment of programs such as identity authentication, security storage, key operation, double offline transaction and the like is provided for a plurality of digital currency wallet trusted applications by depending on a cryptographic algorithm library, a trusted UI (User Interface), a logic engine, a key manager and digital currency wallet basic services. According to the scheme, the security unit is used for protecting the security of the core key, and the trusted execution environment is used for protecting the execution process of the security sensitive program and the security of sensitive information, so that the security unit and the trusted execution environment cooperatively protect related digital assets in the digital currency wallet, and respective technical advantages of SE and TEE are exerted.
