Abstract: For safety authorization to proper security knowledge in mine security knowledge management system and reliable changing of authorization according to users' history access, the reputation-based access control (ReBAC) is proposed, which extends role-based access control (RBAC) with reputation. ReBAC builds 6-tuple permissions firstly. Then, the trust network is constructed by the operational relation between users for calculating direct-reputation and indirect-reputation. After that, ReBAC uses reputation to check if the user can access this security knowledge and give permissions to reliable users. The result shows that ReBAC can provide safety and reliable access control in mine security knowledge management system.

Key words: Access control, Knowledge management, Reputation, Trust network
