Tamper-proof covert communication method and system based on block chain as well as platform

Abstract

The invention discloses a tamper-proof covert communication method and system based on a block chain as well as a platform. The method comprises the following steps: acquiring to-be-sent secret information; adding the secret information into a bit coin transaction by utilizing an OP_Reurn script, so that a new bit coin transaction containing the secret information is formed; broadcasting a signednew bit coin transaction into a block chain system, and storing in a transaction pool; running a block chain mining program, performing a mining operation on the new bit coin transaction in the transaction pool, and packaging and forming a transaction block; by virtue of a POW consensus protocol, saving the transaction block on a block chain; and viewing the transaction block on the block chain, and extracting the secret information. By applying the method disclosed by the invention, external data attached and hidden by utilizing an OP_RETURN script of the block chain is subjected to mining confirmation and then is added into the block chain, thereby guaranteeing that information can not be tampered, realizing integrity and availability of transmitted secret information and guaranteeing safe transmission of the information.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to a block chain-based tamper-proof covert communication method, system and platform. Background technique [0002] The safe transmission of information is the core task of information warfare and secure communication. Encryption and information hiding are two technologies to ensure the safe transmission of information. Encryption makes information incomprehensible, while information hiding makes information invisible during communication, which is a higher level of secure communication. Covert communication, as one of the branches of information hiding, refers to embedding some secret information in images, videos, audios, texts, web pages and other carriers, making it difficult for third parties to perceive the existence of secret information subjectively, which is of great significance to national security and information security. important meaning.

AI Technical Summary

Problems solved by technology

At present, in the communication process of concealed information, there is a problem that it will be intercepted by a third party. If the information cannot be deciphered, the original information will be forcibly tampered with by a third party, resulting in information destruction and affecting the accurate transmission of information.
