Problems solved by technology

[0003] Because there are multiple participants in the supply assurance management process, such as supply operators, maintenance administrators, and library administrators, each participant can perform corresponding operations on supply resources. When resources are operated, it is easy to cause confusion in resource management, thus affecting the accuracy and effectiveness of supply assurance management

Abstract

The invention discloses a block chain-based supply guarantee management method. The specific steps are: first build a blockchain system, assign a private key to each user and calculate the public key, and convert the public key K i Send it to other users in the system; each user stores the initial information of supplying resources in the cloud server; when user R i When it is necessary to operate the supply resource information, use the private key to sign the supply resource information, and send the obtained signature and resource information to other users; other users in the blockchain system use R i The public key and signature of user R are verified i If the verification is successful, each user will update the blockchain system respectively, and if the verification is unsuccessful, the corresponding operation will not be performed. Compared with the prior art, in the present invention, the blockchain system is used to realize supply guarantee management, which ensures the reliability, non-forgery and non-repudiation of supply resources.

Description

technical field [0001] The invention belongs to the field of comprehensive guarantee technology, relates to comprehensive guarantee and block chain intersecting technology, and more specifically relates to a method for realizing supply guarantee management by using block chain technology. Background technique [0002] The elements of comprehensive support include maintenance management, interface design, human resources, supply support, support equipment, technical data, training support, computer resources, support facilities, packaging, loading and unloading, storage and transportation, among which supply support is a very important link . Supply guarantee mainly refers to the supply of spare parts and consumables required for use guarantee and maintenance guarantee within the equipment life cycle according to the integrity of system equipment and cost constraints. Spare parts are used for equipment maintenance and maintenance to replace parts that are faulty or have reac...
