This application provides an authorization issuance method, a permission verification method, a terminal, and a vehicle. The method relates to the field of application permission management. During authorization issuance, the high-risk permission scope of the application to be authorized is obtained. An authorization token is generated by digitally signing the authorization information using a pre-set private key and distributed to the developer for configuration in the application's configuration information. During permission verification, the authorization token is extracted from the configuration information during application installation. A pre-set public key is used for digital signature verification. Upon successful verification, the authorization information is parsed, and the application is checked to determine if it possesses the requested high-risk permissions. If the verification passes, the permissions are granted. This application decouples authorization information from system versions through an independent signature system. The token takes effect immediately upon application version release, solving the mismatch between vehicle firmware update cycles and application iteration cycles. Simultaneously, the vehicle terminal completes signature verification and dynamic authorization offline, achieving lightweight security verification and efficient, flexible permission management.
