Abstract

The invention provides a video coding system of a real-time authentication broadcast data source, belonging to the technical field of communication security. The system comprises a server module and a client module, wherein the server module comprises a video signal input interface module, a coding module and a broadcast data sending module; and the client module comprises a broadcast data receiving module, a data source authentication module and a video signal output interface module. According to the invention, the data source authentication information can be attached to the conventional video information, and the scheme does not obviously extend the coding time or increase the size of the coded file, and thus the effect is satisfactory; and meanwhile, the correctness of the video information is guaranteed to the greatest degree, the video information received by the user comes from a legal sending end for sure, and the attack of criminals and the data loss in channel can be prevented to some degree.

Description

technical field [0001] The invention relates to a video encoding system, in particular to a video encoding system capable of authenticating data sources in real time, capable of performing data source authentication on broadcast video information, resisting insertion and loss of data packets, and belongs to the technical field of communication security. Background technique [0002] Today, with the development of information technology, the security of important information has been paid more and more attention by people. Although there are many information security technologies, most of the existing data source authentication protocols have their limitations. For example, the eSAIDA protocol cannot resist adversary insertion and tampering, and the communication consumption of the PRABS protocol is too large. With the rapid development of video applications today, video security has also received more and more attention. [0003] Conventional video broadcasting cannot perfo...
