Li Ma, Lixin Tao, Yong Zhong, Keke Gai · 2016
Current rapid increasing implementations in data diversity, autonomy and dynamic privilege management, fine-grained access control in social networks have resulted in various challenges in applying existing access control models. We focus on this issue and propose a new social network access control model, RuleSN, using logical authorization language. The model provides high performance of authorization expressiveness and flexibility that can perfectly describe relations of User to User (U2U), User to Resource (U2R), Resource to Resource (R2R) and attributes of users and resources. First, this paper elaborates the formal definitions of the RuleSN model. Second, we describe the model's authorization specification and verification policies and explain the syntax and semantics of the authorization language. Finally, the implementation, application and expressiveness of the model discussed by examples.
