The invention discloses an ARM TrustZone-based mobile terminal security service method and device, and relates to the field of communication technology. The method includes: obtaining a source file ofan application program of a normal world when a safe world starts up, and determining a first hash value of the source file by using a hash algorithm; obtaining a calling instruction, file information and the first address of the application program by using a security agent located in the normal world; sending the file information, the first address, the first hash value, and a first point in time when the secure world is running to a server so that the server saves the file information, the first address, the hash value, and the first point in time; and obtaining the second hash value of the application program in the normal world through the verifiable computer system VC by the server, and determining the integrity of the application program of the normal world in the initial state andthe startup state, where the second hash value represents the initial state of the application program.
Description
technical field [0001] The present invention relates to the field of communication technology, and more specifically to an ARM TrustZone-based mobile terminal security service method and device. Background technique [0002] Mobile applications have entered a stage of explosive growth, which provides great convenience for users to enjoy Internet services. Mobile applications such as mobile payment are becoming more and more popular in work and life, but users also increasingly hope to use a secure mobile execution environment Protect secret behavior and data in apps. [0003] In order to effectively build a mobile trust execution environment, the typical TEE (English: Trusted Execution Environment, Chinese: Trusted Execution Environment) technology has proposed a security verification method for the local device, but these methods hope to provide a basis for trust in the underlying system. , and create a trusted verification chain for advanced applications. In addition, so...
