Security certification method for accessing extended function module into network mobile terminal

Abstract

The invention provides a method for performing security certification on an extended function module of a network mobile terminal. The method comprises the following steps that: a plug-in extended module a for updating application functions is accessed into the network mobile terminal; a plug-in manager transmits an identification request to an application program manager; the application program manager acquires a digital watermark on the plug-in extended module a, and an operating system driving layer generates an additional key; the additional key is transmitted to a security chip to verify source authentication and authority authentication; if the verification succeeds, an operation request is transmitted to the application program manager, and the application program manager permits the plug-in extended module a to be loaded and installed; and if the verification fails, the permission of the application program manager cannot be acquired, and the plug-in extended module a cannot be loaded and installed.

Description

technical field [0001] The invention relates to a method for providing security authentication for mobile terminal access in the technical field of network access security authentication. Background technique [0002] The next generation network (NGN) provides open application programming interfaces to end users to meet individual needs. The demand for various extended application functions of network mobile terminals is increasing, and the security authentication technology for extending application functions and transmitting information is the core technology. [0003] Relevant patents or patent applications obtained through retrieval are: [0004] A secure access method for a mobile terminal in a wireless local area network (patent number: 02139361), which relates to a secure access method for a mobile terminal in a wireless local area network. The MT and the wireless access point AP perform two-way identity authentication. [0005] A method for secure access and secur...

AI Technical Summary

Problems solved by technology

[0007] The above patents only involve a secure access authentication method for a certain application, which cannot be used universally for different types of extended functions, and requires high compatibility and stability of terminals and programs; security authentication cannot be achieved for terminal devices communicating between different networks For expansion, devices need to be converted through proprietary protocols. High deployment costs occupy a large amount of terminal resources, and are not suitable for large-scale deployment.
