Cross-organization access control method based on alliance chain and multiple signatures

Abstract

The invention relates to a cross-organization access control method based on an alliance chain and multiple signatures, and belongs to the technical field of block chains. According to the method, a non-centralized alliance chain technology is used as a trusted machine, distribution, updating and recovery of cross-organization access control authority are realized under the condition of no participation of a centralized third party, and authorization decision is carried out on a cross-organization access request based on an alliance chain intelligent contract. A single-point fault of the centralized node or malicious tampering of the access control authority can be effectively prevented. According to the method, participant nodes are added or removed based on an alliance chain admission mechanism, contract logic is deployed or updated, the method is effectively used for dynamic joining of participants and business logic change in a resource sharing system, and good expansibility is achieved. On the basis of a multi-signature technology, multi-party management control over the co-governance service is provided, and a group of role sets belonging to multiple organizations can jointly manage one co-governance service.

Description

technical field [0001] The invention relates to a cross-organization access control method based on alliance chains and multi-signatures, and belongs to the technical field of block chains. Background technique [0002] Modern engineering activities present a trend of becoming larger, more complex and more diversified. Through the collaborative work of employees belonging to different enterprises and organizations, the advantages of each enterprise can be fully utilized, the development efficiency of engineering activities can be improved and the development cost can be reduced. [0003] The key to the collaborative work of different enterprises and organizations is to realize the sharing of data, computing and storage resources by all parties, improve the overall collaboration efficiency, and make full use of the shared resources of all parties. In order to improve the efficiency of multi-enterprise collaboration, it is necessary to realize cross-organizational sharing and...
