Blockchain-based power data security information system

Abstract

The invention relates to a blockchain-based power data security information system. The system includes a database, a bottom-layer blockchain subsystem, and an upper-layer service application subsystem which are distributed sequentially from bottom to top; the database is used for storing data corresponding to a blockchain ledger; the bottom-layer blockchain subsystem is used for providing messagequery, message feedback and log query functions to the upper-layer service application subsystem in the form of interfaces, and includes a plurality of peer nodes, a consensus node, and a blockchainledger, wherein the peer nodes generate the blockchain ledger corresponding to the consensus node according to the content of the consensus node; and the upper-layer service application subsystem provides a data access interface by using a Restful-based unified interface mode, and communicates with the peer nodes of the bottom-layer blockchain subsystem through the access interface. Compared withthe prior art, the system of the invention has the advantages of no central data management, non-tampering property, audit fairness, port security shielding and the like.

Description

technical field [0001] The invention relates to the field of power data communication, in particular to a block chain-based power data security information system. Background technique [0002] With the continuous improvement of power system informatization, there are a large number of application systems in the power network, and each application system has a large number of system interfaces for other systems to call, facing the following security issues: [0003] 1) Provide services to other systems by exposing ports, which brings security risks. [0004] Traditional information systems provide services in ways such as Webservice, Http Rest, and JMS. These methods require the application system to expose relevant ports and access addresses, which can easily bring security risks to the system and various network attacks, such as malicious interfaces. Problems such as calls and sql injections put pressure on system security operation and maintenance. [0005] 2) Data inco...

[0003] 1) Provide services to other systems by exposing ports, which brings security risks

[0004] Traditional information systems provide services in ways such as Webservice, Http Rest, and JMS. These methods require the application system to expose relevant ports and access addresses, which can easily bring security risks to the system and various network attacks, such as malicious interfaces. Problems such as calls, sql injection, etc., bring pressure to system security operation and maintenance

[0005] 2) Data inconsistency caused by business cross-system flow

[0007] Take the PMS2.0 distribution network emergency repair order as an example, the user reports for repair through the 95598 hotline, the work order is generated from the 95598 system, then enters the marketing CMS system, and then enters the PMS2.0 interface server. Corresponding assessment requirements, analyzed from PMS2.0 labor dispatch overtime work orders, the interface audit logs provided by each system do not correspond to the time, and each system cannot provide audit logs that are convincing to other systems
