【 摘 要 】

In this paper, a knowledge-based approach to Internet authorizations is proposed by using Public-Key Infrastructure (PKI) based digital certificates, trust models, Role-Based Access Control (RBAC), and intelligent backtracking. Security policies are expressed as the rules in a knowledge base. An inference engine is utilised to evaluate policies, dynamically assign roles to Internet users, and redo roles assignment automatically. 12 Pages
