A method and system for secure data transmission based on terminal trust management

Abstract

The present invention relates to a method and system for secure data transmission based on terminal trust management. The method includes: when a terminal to be evaluated applies for accessing a video conferencing system, determining a benchmark trust value of the terminal to be evaluated according to a historical trust value; determining a terminal to be evaluated In the historical interaction with the network center, the rate of data security transmission and the rate of initiating attacks; according to the rate of data security transmission and the rate of initiating attacks, determine the self-assessment trust value of the terminal to be evaluated; through the network center, collect and evaluate the terminal The evaluation of the terminal to be evaluated by the terminal that has interacted; determine the other-evaluation trust value of the terminal to be evaluated according to the evaluation set; determine the behavior trust value of the terminal to be evaluated according to the self-evaluation trust value and other-evaluation trust value; Determine the global trust value of the terminal to be evaluated; determine whether the terminal to be evaluated is allowed to access the video conference system according to the global trust value. The invention improves the security of data transmission.

Description

Technical field [0001] The present invention relates to the field of data secure transmission technology, and more particularly to a data secure transmission method and system based on terminal trust management. Background technique [0002] Video conference is a conference method that allows multiple users from different places to interpire video, file materials, and implement real-time conference methods through network and multimedia equipment. Compared with the ordinary face-to-face meeting, the video conference has been favored by many companies with its advantages of increasing the cost of the company due to no need to flow due to no personnel flow. In addition, because of the above advantages of video conferencing, some government agencies, medical systems, education systems, etc. have gradually begin to apply video conferencing systems. Therefore, the video conference method is rapidly occupying the highland of new office methods, and its popularization will be a trend. ...

Problems solved by technology

[0003] After research and analysis, it is found that the main reason for data transmission security problems is: the network side unconditionally trusts the terminal accessing the conference, and the terminals connected to it are trusted by default, and all their behaviors are trusted; however, malicious terminals will use This "implicit trust" initiates attacks such as denial of service attacks, monitoring, tampering with meeting content, etc.

This is equivalent to destroying the security of data at the source of data transmission, even if the security of data transmission technology is higher in the subsequent transmission process, it will not help
