A method and system for random key transmission under multi-link conditions

Abstract

The present invention discloses a method and system for random key transmission under multi-link conditions. The method includes: obtaining a first key to be transmitted, encrypting the first key to be transmitted, and obtaining the processed The second key to be transmitted, convert the second key to be transmitted into the format of link transmission, obtain N preset links, determine the start node and end node corresponding to each preset link, and activate N links at the same time A preset link, a preset random selection algorithm selects a target start node and a target end node among N start nodes and end nodes, and passes the format-converted second key to be transmitted through the target start node and target The first target preset link corresponding to the termination node is used for transmission. By randomly assigning the key to be transmitted to multiple links for transmission, the process of allocating the transmission link can not be mixed with artificial emotional factors, and avoids the key leakage caused by key leakage. The loss of more files leads to the problem of significant property damage.

Description

technical field [0001] The invention relates to the technical field of key protection, in particular to a method and system for randomly transmitting keys under multi-link conditions. Background technique [0002] Cryptography technology is the basic technology of information security, and the key is the basis of secure application of cryptography technology and the core element of information security. With the rapid and comprehensive development of my country's information industry, the key management system based on the symmetric key system has also entered a comprehensive construction stage, and the key transmission process involved in the system is facing more and more stringent security requirements. The key transmission method in the existing communication technology is to encrypt the key and then transmit it through the preset communication link, so that two devices can realize the transmission of the key in this way, but this method exists The following disadvantag...
