Research on Application of Permission Management Method Based on RBAC Model in Collaborative Platform

Spacecraft multi-disciplinary collaborative design requires a complex collaborative design platform. During the process of multi-disciplinary collaborative design, there are complex management relationships among projects, tasks, data, roles, users, and permissions. Permission management of the collaborative design platform has become the core content of the system, In situations where there are no permissions or improper management of permissions, issues such as unreasonable resource allocation, important data leakage, role-permission conflicts, and system security threats can arise. In the Role-Based Access Control (RBAC) model, the complexity of role inheritance relationships may lead to multiple judgments regarding permissions, This will increase system expenditure and trigger conflicts, leading to a significant drop in user experience. This paper, based on practical applications, describes a flexible and secure role management method for permission management designed within the RBAC model for a large collaborative design platform in the aerospace field. It achieves collaborative project management with considerable practicality.
