Stream data transmission anti-disclosure method and system based on coding

Abstract

The invention discloses a stream data transmission anti-disclosure method and a stream data transmission anti-disclosure system based on coding. The method comprises the following steps: counting thedata domain length of each data frame in a historical network stream data file to obtain a frame length distribution sequence; obtaining a hierarchical threshold list from the frame length distribution sequence; generating filling bit data based on the data domain length of the to-be-processed data frame and the normalized hierarchical threshold list; performing null value filling and matrix bottom filling on the to-be-processed data frame based on the null value filling bit and the filling bit data to obtain a matrix after row filling and confuse the matrix; performing hash filling on the confused matrix by adopting a hash function to obtain an encrypted data frame, and transmitting the encrypted data frame; and enabling the receiving end to divide the received encrypted data frame into abit data part matrix and a hash value part matrix, and obtaining an original data frame after hash value verification, filtering and removal of data frames filled at the bottom of the matrix in the filtered matrix. According to the invention, attackers can be prevented from counting and classifying streaming data frames on a network level to obtain user private information.

Description

technical field [0001] The invention relates to the field of secure transmission of streaming data, in particular to an encoding-based method and system for preventing leakage of streaming data transmission. Background technique [0002] With the development of communication technology and multimedia technology, people are increasingly dissatisfied with the communication of text and voice, and the application of network multimedia mainly based on video conferencing is becoming more and more extensive. At the same time, the large-scale popularization of the fifth-generation communication technology has also made the video conferencing system more intelligent, efficient, convenient and fast, which not only comprehensively improves the informatization level of various industries, but also enables zero-distance communication between all parties. Video conferencing is a conference service that provides real-time audio and video transmission between remote and multiple points. Mul...
