Information distribution method for mobile terminal

Abstract

The present invention relates to an information distribution method of mobile terminal; in the process of mutual authentication between a mobile terminal and a network server, the mobile terminal sends the relevant information code of the mobile terminal to an authentication server; after the authentication succeeds, a session key is established; the authentication server sends the relevant information code of the mobile terminal to the network server; according to the relevant information code of the mobile terminal, the network server completes the operation of information distribution and returns operating results to the authentication server; the authentication server informs the mobile terminal of the authentication and the information distribution results. With the method of the present invention, the information distribution is embedded to the AKA process, reduces the communication cost and can reduce omissions and errors of information distribution by the network server as possible; the present invention can use the session key consulted in the authentication process to encrypt distributed information and reduces the probability of being attacked. The key consulted in the AKA process has safe protection on data distribution and improves the safe performance.

Description

technical field [0001] The invention is applicable to the fields of mobile communication and information security, and specifically relates to a method for information distribution by a network server to a mobile terminal. Background technique [0002] With the development of mobile networks from 2G to 3G and the integration of various wireless LAN access methods, the services based on multimedia transmission are increasingly diversified, the data volume of media streams is increasing, and the real-time requirements are high. The security guarantee mechanism can no longer adapt to this development trend. Therefore, the mobile network needs to provide a technical mechanism so that the terminal can accept the necessary security management and control from the network. For example, by installing various agents on a mobile terminal, services on the network side can be closely integrated with terminal service applications to form a whole. [0003] In the mobile network, the dist...

Problems solved by technology

Similar to security policies, information that needs to be stored on each mobile terminal using security services, it is expensive to establish a separate connection for the distribution of such information each time. An existing technology is to Frequently used software modules need to be fixed to mobile terminals, but this is obviously not suitable for information data that needs to be updated in real time, such as security policies

In addition, due to the uncertainty of the location and status of the mobile terminals, the server cannot guarantee that all mobile terminals store the latest information data at the same time, which brings difficulties to subsequent communications.
