Terminal, server and establishment method of communication connection

Abstract

The invention provides a terminal which comprises a connection establishment unit used for establishing connection between the terminal and a server, a secret key request unit used for sending a secret key acquisition request into the server, a data acquisition unit used for acquiring a connecting secret key corresponding to the secret key acquisition request from the server, a command generation unit used for enabling the link address of the server and the connecting secret key coming from the data acquisition unit to generate a connecting short message command; a command sending unit used for sending the connecting short message command coming from the command generation unit into a second terminal. Correspondingly, the invention also provides the server and an establishment method of communication connection. After the technical scheme is adopted, a user can independently select the communication server and security protocol, so that the safety of the communication process can be improved, and the communication data of the user can be better protected.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a terminal, a server and a method for establishing a communication connection. Background technique [0002] At present, communication between mobile terminals is mainly realized through the following methods: [0003] The terminals of the two parties register IDs on the intermediate server, and all terminals must log in to the fixed intermediate server with the ID. As long as one end does not register the ID in the intermediate server and log in to the server connection in advance, communication cannot be carried out. However, a fixed public server is not necessarily reliable for the receiver, and this intermediate server is fixed, and it is impossible to set up a server (such as the server of your own company) that the designated receiver feels safe at any time, and it cannot be established from the beginning of the communication connection. Using the security p...

[0003] The terminals of the two parties register IDs on the intermediate server, and all terminals must log in to the fixed intermediate server with the ID. As long as one end does not register the ID on the intermediate server and log in to the server connection in advance, communication will not be possible

However, a fixed public server is not necessarily reliable for the receiver, and this intermediate server is fixed, and it is impossible to set up a server (such as the server of your own company) that the designated receiver feels safe at any time, and it cannot be established from the beginning of the communication connection. Use the security protocol specified by the receiver to communicate. The receiver may worry that the received things have been tampered with in the middle, and the security, immediacy and flexibility are relatively poor.
