Threat information exchange sharing method based on block chain

Abstract

The invention discloses a threat information exchange sharing method based on a block chain, and the method comprises the steps: 1),a threat information block chain system is set with the system comprising comprises a threat information block chain, a synchronization node, and a plurality of maintenance nodes; a user registers as a threat information block chain user, and obtains a corresponding public key and a corresponding private key; 2) a threat information producer sets intelligent contract content on the system, signs the intelligent contract content with a private key and then issues the intelligent contract content to a threat information block chain; 3) the intelligent contract content signed issued by the information consumer synchronously is threatened, a private key used to sign and the content is broadcast through the system; 4) a maintenance node analyzes the content in the smart contract and packages the content into a new threat information block A; 5) a block A is broadcasted to the system, the maintenance node adds the block A to the threat information block chain after consensus of the block A is achieved, and 6) the maintenance node achieves consensus after confirming the effectiveness of the smart contract, creates a new block B and broadcasts a new block B through the system.

Description

technical field [0001] The invention discloses a method for exchanging and sharing threat information based on block chain, which realizes the confidence, timeliness, matching degree and correlation degree of threat information by using the decentralization mechanism, consensus algorithm and non-tamperable modification of block chain The controllability of key indicators, such as key indicators, has changed the traditional mode of threat intelligence exchange and sharing through the token incentive mechanism, which has greatly promoted the quantity, quality and enthusiasm of threat intelligence producers to supply intelligence, and also greatly promoted the threat intelligence. Efficient consumption and high value utilization. Background technique [0002] The existing threat intelligence exchange and sharing models mainly include open source threat intelligence exchange and sharing and commercial threat intelligence exchange and sharing. Open source threat intelligence pro...

Problems solved by technology

Open source threat intelligence provides a large amount of effective intelligence for public welfare and other purposes, but the coverage, timeliness, accuracy, etc. Provided by producers, there is still a lack of unified and automated evaluation standards in terms of intelligence supply capabilities, feedback capabilities, and emergency response capabilities, which brings threat intelligence consumers the problem of lack of quantitative standards for threat intelligence evaluation effects
