An Authorization Model for Multi-classification Interconnected System

摘要：

Focusing on the authorization security when subject accesses object in Multi-classification Interconnected System (MCIS), an authorization model which can support multi-ply security policies is proposed. In this model we introduce three authorization constraint conditions: system security classification, information security classification (subject clearance level, object sensitivity level), and different authorization types. We give the mapping functions realizing the mapping relation between the information security label and security classification, and also give the conflict and resolution rules in order to keep consistency of the authorization model. Finally the security of the authorization model is analyzed.
