Embodiment

[0037] Please refer to image 3 , which is a schematic flowchart of a method for controlling a terminal entering a secret call according to an embodiment of the present invention. Such as image 3 As shown, the terminal steps as follows:

[0038] Judging whether the end handshake flag is received, if yes, the terminal enters the secret call state.

[0039] In this embodiment, the terminal is the communicating parties for secure communication, including the first terminal and the second terminal, and the key server can simultaneously send the handshake end flag to the first terminal and the second terminal.

[0040] Specifically, the key server may use a data link to send the end handshake flag to the terminal. When performing secure voice communication, the data link is a 12.2k voice link; and when performing secure video communication, the The above data link is a 64k video link. In addition, when the secure communication parties are conducting secure video communication,...

Abstract

The invention provides a method for controlling a terminal to enter a secret communication, a secret communication method and a terminal for secret communication. The terminal judges whether a handshake terminating mark is received, if so, the terminal enters the secret communication. The terminal judges whether the handshake terminating mark is received to control the time when the terminal enters the secret communication, so that the secret communication parties can achieve the synchronization and the secret communication can be implemented.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control method for a terminal to enter a secret call, a secret communication method and a terminal for secret communication. Background technique [0002] With the rapid development of modern communication technology, means of threatening the security of communication networks such as network hackers and network interception tools are also emerging. estimated loss. Therefore, how to realize the secure communication of the communication network has become a hot research topic nowadays. [0003] At present, in order to realize the secure communication of the communication network, the general practice in the industry is to encrypt the communication data and carry out confidential communication, so that even if the third party intercepts the communication data through improper means, because the communication data has been encrypted, the third party cannot easily The spec...
