Data security transmission method and system suitable for satellite mobile communication terminal

Abstract

The invention relates to a data security transmission method and system suitable for a satellite mobile communication terminal, and the method comprises the steps that a calling satellite mobile terminal comprises a first security unit and a first communication unit, wherein a called satellite mobile terminal comprises a second security unit and a second communication unit; the first security unit acquires communication service data generated by the first communication unit, performs security processing on the communication service data according to the first application lock state to generate security-processed communication service data, and sends the security-processed communication service data to the first communication unit; the first communication unit sends the communication service data after security processing to a second communication unit through a satellite channel; and the second security unit obtains the communication service data after security processing, carries out security analysis on the communication service data according to the state of the second application lock, generates analyzed communication service data and sends the analyzed communication service data to the second communication unit. Therefore, when the plurality of communication units call the security unit at the same time, the communication service data can be safely processed and transmitted orderly.

Description

technical field [0001] The invention relates to the technical field of satellite mobile communication, in particular to a method and system for secure data transmission suitable for satellite mobile communication terminals.
