Anti-protocol analysis data security transmission method, system, information data processing terminal

Abstract

The invention belongs to the technical field of data security transmission, and discloses an anti-protocol analysis data security transmission method, system, information data processing terminal, a client uploads file data, and completes random size splitting, marking, encryption, and transmission protocols of files to be transmitted Dynamic switching; the client requests to download the file required by the user, requests to download the file with the same name on the server of different transmission protocols, and accepts the file data sent by the server of different protocols; the server processes the data uploaded by the client, receives the file data uploaded by the client, and Decrypt and organize the file data; the server processes the download request from the client, encrypts the file data required by the client and sends it to the client. The present invention can realize the covert transmission of file data under the condition of listeners; realize the safe transmission of data in the public network environment, defend against the traffic analysis attacks that may exist in the data forwarding nodes of the public network, and improve the security of data transmission.

Description

technical field [0001] The invention belongs to the technical field of data security transmission, and in particular relates to a method, system, and information data processing terminal for anti-protocol analysis data security transmission. Background technique [0002] At present, the closest existing technology: With the rapid development of computer and communication technology and the continuous expansion of Internet applications, today's society is already in a highly informational era, and all kinds of information are extremely important to people's life and work. role. With the development and expansion of the entire Internet, the scale of the communication network continues to expand and the environment becomes more and more complex, which poses great challenges to the safe transmission of information and data in an open network environment. In the process of network transmission of data information, it is necessary to face problems such as complex Internet environ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: the transmission protocol used in the transmission process of the same kind of information data is single, resulting in a single traffic characteristic, and it is impossible to defend against illegal traffic analysis behaviors existing in the public network environment; during the data transmission process, It is impossible to adjust the dynamic anti-traffic analysis countermeasures according to the changes of the network environment; the large file transfer behavior between users makes the communication traffic between the two parties huge, and an efficient transmission method is required
