Malicious website collaborative detection strategy based on blockchain technology

Abstract

The invention discloses a malicious website collaborative detection strategy based on a blockchain technology, and the strategy mainly comprises the steps: firstly, a blockchain private chain is builtto form a collaborative detection synchronization environment; secondly, each node in the blockchain environment can be used as a participant and a beneficiary for malicious website collaborative detection; when a certain node accesses a malicious website, the detailed information of the accessed malicious website can be used as a record to be stored in the block chain through a workload certification mechanism; all nodes in the blockchain synchronize malicious website information detected by each blockchain node by jointly maintaining a data account book, and a warning is given when other nodes access existing malicious websites in the blockchain. According to the scheme, the block chain technology is combined, a malicious website detection environment based on the block chain technologyis formed through a workload proof mechanism, the effectiveness and tamper resistance of malicious website information are guaranteed, the collaborative defense effect is achieved, and the network security is effectively improved.

Description

technical field [0001] The invention relates to a collaborative detection strategy for malicious websites based on block chain technology. Aiming at the current frequent occurrence of network security incidents and the fact that individuals alone cannot form an effective collaborative detection system, a collaborative environment is formed by building a block chain private chain. The proof-of-work mechanism of the block chain collects the known malicious website information of each node participating in the collaborative detection strategy to form a collaborative detection system. When a computer node accesses a known malicious website in the blockchain, it issues a warning, effectively Improve the detection and defense efficiency of malicious URLs and the security of computer networks Background technique [0002] In the current society, with the rapid development of computer technology, the Internet has become an indispensable part of people's lives. The coverage of the In...

Problems solved by technology

[0005] Although collaborative defense can effectively improve the detection efficiency, there are still some problems in the traditional collaborative defense method. In terms of data forwarding, the current malicious URL collaborative detection system mostly shares known malicious URL information between nodes through message forwarding, which is affected by A large network impact will also bring a certain amount of traffic overhead; in terms of data sharing, many users are concerned about their own confidentiality, and do not want to hand over their known malicious information to other unfamiliar participants at will. How can untrustworthy users Passing information between and ensuring the integrity of the information is a big challenge
