Universal IP traceability system and method based on block chain

Abstract

The invention belongs to the field of network security, and particularly relates to a universal IP traceability system and method based on a block chain. The system is divided into a data acquisition layer, a traceability service layer, a traceability supervision layer and a traceability coordination layer, and a credible service-oriented universal IP traceability system is provided by referring to a business mode of immediate collection and immediate payment in a block chain so as to promote large-scale deployment of the traceability system; the traceability supervision layer comprises a data module, a consensus module and a verification module; the data module simplifies block data, the consensus module improves the working efficiency and performance of the block chain and reduces the deployment cost, and the verification module prevents malicious nodes from tampering transaction information and ensures the data integrity. The traceability method comprises a traceability trace establishment stage and an attack path reconstruction stage. A concurrent backtracking mechanism is adopted, so that the traceability efficiency is improved; the system is also suitable for a traceability method based on a data packet, is compatible with most of current IP traceability methods, and has universality.

Description

technical field [0001] The present invention relates to the field of network security, in particular to a general IP traceability system and method based on a block chain architecture. Background technique [0002] Nowadays, the Internet has become a part of human life, but while the Internet facilitates life, it also brings some crises. The network is full of various IP anonymous attacks, such as D(D)oS attacks and ransomware attacks. The root cause of such cyber attacks is the stateless operation of the Internet. At the same time, due to the stateless nature of the Internet and the fact that attackers can arbitrarily forge the source address field in the IP header that uniquely represents their identity, it is extremely difficult to trace the source of cybercrime. Therefore, in order to fundamentally prevent such attacks, a tracking mechanism must be established in the network to collect information about the path of data packets so as to change the stateless nature of t...

Problems solved by technology

However, the above cloud server-based IP traceability architecture does not fully consider the commercial relationship between autonomous domains, and defaults to a friendly and cooperative relationship between autonomous domains. This assumption is obviously unrealistic and is not conducive to the actual deployment of the traceability system.

In terms of the traceability mechanism, the existing technology adopts a "serial" access mechanism, which still has deficiencies compared with the "concurrent" access mechanism
