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 supply guarantee management method based on a block chain. The method comprises the following specific steps: firstly, constructing a block chain system, allocating a privatekey to each user, calculating a public key, and sending the public key Ki to other users in the system; enabling each user respectively to store the initial information of the supply resources in thecloud server; when the user Ri needs to operate the supply resource information, signing the supply resource information by using the private key, and sending the obtained signature and resource information to other users; and enabling other users in the blockchain system to verify the identity and resource information of the user Ri by using the public key and signature of the Ri, enabling eachuser to update the blockchain system if the verification succeeds, and not performing corresponding operation if the verification fails. Compared with the prior art, the supply guarantee management isrealized by using the blockchain system, and the reliability, unforgeability and non-repudiation of the supply resources are ensured.

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...
