Abstract

The invention provides a role access control system based on a block chain smart contract. According to RBAC rule setting, the role access control system based on the block chain smart contract is logically divided into a data layer, an access control layer and a presentation layer, and the role access control system based on the block chain smart contract is divided into a user module, a role module and an authority module according to function modules. The invention further provides a role access control method. Contract deployment, administrator initialization and role and authority configuration need to be completed before the access control system is used; and then, the user can perform login, a manager can do works such as audit and role distribution. The role access control method comprises the following steps: 1, deploying an intelligent contract of a role access control system based on a block chain intelligent contract in a block chain system; 2, configuring permission and roles; 3, the user registering an account; 4, auditing user registration; 5, the administrator allocating roles to the users; and 6, the user logging in and accesses the system by using the secret key.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a role access control system and method based on block chain smart contracts. Background technique [0002] In today's Internet era, especially the mobile Internet era, information technology has brought unprecedented changes to human society and daily life. At the same time, the importance of information security is also increasing. It is necessary to effectively prevent misuse, man-made damage, data leakage, etc., and complete the effective isolation of information so that people with different roles can only see and operate data that belongs to their own authority. . This involves the access control function, which can restrict users' access to and operations on resources by setting the relationship between users, roles, permissions, and operations. The role-based access control model RBAC (Role-Based Access Control) is favored by academia and industry as a general rule...
