Embodiment 1

[0032] This embodiment provides a blockchain-based electric power industry electronic data security system, such as figure 1As shown, it includes a power business system, a blockchain platform, and a CA organization; the power business system is connected to multiple clients, and the clients use the digital certificate in the USBKEY to log in to the power business system for operation, and use the private key in the USBKEY to log in to the power business system to operate. The key signs the operation information. The plurality of client terminals are common client terminals, notary office terminals and judicial authentication agency terminals.

[0033] From traditional centralized storage of electronic data to blockchain platform storage; the blockchain platform includes sorting service nodes, multiple endorsement nodes and multiple transaction nodes, and the endorsement nodes in the blockchain platform use verification power The two-time verification signature method of the ...

Embodiment 2

[0038] This embodiment provides a blockchain-based electronic data preservation method in the electric power industry. The present invention adopts the method of verifying the signature twice to realize the verification requirement of the operator's identity on the block chain platform. The user locally uses the private key in the USBKEY to sign the preserved data. After the signature is sent to the power business system, the power business system will also use its own private key to sign the core data. Finally, after all the information containing the preserved data is transmitted to the endorsement node of the blockchain platform, the endorsement node not only needs to verify the validity of the server certificate of the power business system and the user's digital certificate, but also needs to verify the signature data of the power business system and the user's signature data. Only after the above verifications are passed, the endorsement node will simulate the transacti...

Abstract

The invention discloses an electronic data preservation method and a system for a power industry based on a block chain. The security system of the invention comprises a power service system, a blockchain platform and a CA mechanism. The electric power service system is connected with a plurality of user terminals. The invention redesigns the verification flow of the endorsement node, which not only verifies the signature of the electric power service system, but also verifies the private key signature of the operator at the user end, so that the identity and operation of the user end are verified inside the block chain platform. This design allows the endorsement node to confirm the identity of the client operator directly, as a direct condition to generate the corresponding authority ofthe transaction endorsement, which is more secure and reliable, and can not be tampered with. Moreover, the electronic business system reduces the verification operation, and can greatly improve theefficiency of service invocation. In addition, the client uses USBKEY hardware for cryptographic operation, the private key can not be out of the hardware, so that the electronic raw data generation and transmission of the client is more secure.

Description

technical field [0001] The invention belongs to the technical field of block chains, in particular to a block chain-based electronic data preservation method and system in the electric power industry. Background technique [0002] Electronic data security in the energy and power industry is very important and widely used consistently. Electronic data preservation uses cryptography-related technologies to digitize various information such as contracts, contracts, and data, and then uses electronic signature technology to digitally sign these electronic data to achieve the purpose of non-repudiation and unalterability, thereby facilitating justice. Use in applications such as forensics. [0003] At present, the common electronic data preservation of power system involves four subjects: power service provider, ordinary user, notary office and judicial authentication institution. Among them, power service providers provide comprehensive power services to the outside world, and...
