The invention discloses a security management method and a system for the vehicular mobile Internet. When an application program accesses a vehicular terminal, the vehicular terminal judges the authorization of the application program. When the authorization of the application program is the runtime authorization of a local access, the application program directly accesses the vehicular terminal information. When the authorization of the application program is the remote authorization of a remote access, the vehicular terminal authenticates the access authority of the application program through a server side. If the authorization is passed, the application program accesses the vehicular terminal information. The server side provides register, application, safe key management and application audit service for application developers of a third party, and the application access authority of the third party is saved in the server side. Through the interaction of the vehicular terminal and the server side and the own management of the vehicular terminal, the method and the system adopt a high-efficiency authentication mechanism and an encryption communication mechanism, so that the safety management of vehicular application is easily realized, and the critical data of the vehicular terminal cannot be embezzled by illegal application. Thus, a car accesses the mobile Internet to share the convenience and fast of the network, and while the privacy data of users cannot be stolen.
