Block chain system-oriented information security detection method

Abstract

The invention discloses an information security detection method for a block chain system, and the method comprises the steps: sequentially triggering protocol layer intelligent detection, implementation layer intelligent detection, use layer intelligent detection and system layer intelligent detection from algorithm layer intelligent detection after the security detection is triggered, the detection steps adopted by each level are as follows: identifying and evaluating input or intercepted message information; analyzing the detection content of unknown existence of vulnerabilities, and realizing collection of vulnerability information at the same time; logs and blocks are generated, and data storage and transmission are achieved. According to the systematic block chain security detection method, the algorithm layer intelligent detection, the protocol layer intelligent detection, the implementation layer intelligent detection, the use layer intelligent detection and the system layer intelligent detection are triggered in sequence, so that the security detection of the whole block chain system is realized; according to the invention, the research blank in the field of block chain security at home and abroad is filled up to a great extent.

Description

Technical field [0001] The present invention belongs to the field of block chain information security technology, and in particular, it is related to a block chain system information security detection method. Background technique [0002] As a kind of emerging technology, the block chain will inevitably face unknown risks and vulnerabilities, and because the application of the block chain is concentrated in high-value fields such as finance, the loss is often huge, for example, in 2016 In June, the THE DAO crowdfunding project lost nearly 60 million US dollars due to the re-entry vulnerability of intelligent contract calls, according to the statistics of the national block chain drain cave, the economy caused by the internal block chain security vulnerability incident The loss is up to $ 17.9 billion, an increase of 130% from 2019. With the wideness of the block chain, the hacker's attack method is also constantly updated and improved. [0003] From the perspective of existing d...

AI Technical Summary

Problems solved by technology

[0003] Judging from the existing research fields at home and abroad, blockchain security issues mainly exist in the following aspects: cryptography mechanism loopholes; consensus protocol attacks; smart contract code vulnerability threats; privacy security issues; system security issues , the research on security detection is more focused on the vulnerability detection of smart contract codes. A summary and comparison have been carried out, however, the problem of security vulnerabilities exists in the entire blockchain system. At present, the research on related detection technologies is not systematic and comprehensive, and there is no security detection method for the entire blockchain system.
