Terminal security legality verification method

Abstract

The invention discloses a terminal security legality verification method. The method comprises the following specific steps: firstly, verifying a software flag bit switch state; defining that a user name part of a service routing message in a 200OK signaling of a boundary session controller or a proxy call session control entity responding to a user terminal is obtained by coding a branch parameter in a Via header field through an MD5 algorithm; and after a user terminal receives the successfully registered 200 OK signaling, coding a branch parameter in the Via header field by an MD5 algorithm and then comparing the same with the user name part of the service routing message by using an encryption mapping algorithm, returning registration success if the coded Branch parameter is consistent with the user name part of the service routing message, or returning network authentication failure if the coded Branch parameter is not consistent with the user name part of the service routing message, and sending a logout message to logout the user. According to the method, the application field of the IMS equipment is expanded, the compatibility of the equipment and the sensing of the service used by the user terminal are improved, the original processing flow of the equipment is not influenced, and the method has the advantages of being simple in algorithm, high in working efficiency and capable of increasing the adhesiveness and the safety of the use of the user.

Description

technical field [0001] The invention belongs to the technical field of ad hoc networks, and in particular relates to a method for verifying the validity of terminal security. Background technique [0002] With the rapid development of the Internet, more and more people pay attention to the information security of terminals and networks, and the requirements for terminal security and network security are getting higher and higher. To better protect the existing investment and subsequent benefits, it is necessary to solve the mutual verification of the legitimacy between the terminal and the network equipment. [0003] At present, the existing encryption process requires special encryption equipment and encryption algorithm to generate the key. The encryption algorithm is complex and the process of generating the key is cumbersome, which requires a lot of resources to complete, and an encryption channel is established during the data encryption transmission process. The key i...
