摘要

The traditional approach to information sharing focuses on attaching attributes and policies to an object as it is disseminated from producers to consumers. In contrast, group-centric sharing brings subjects and objects together to facilitate sharing in a group. In such contexts, subject and object join a group without constraints and authorisation is just influenced by the temporal ordering of subject and object in the group. We believe that a subject must get some privileges while joining a group and authorisation is also influenced by the trust level of subject and the security level of object. In this paper, a novel model for Group-Centric Secure Information Sharing (g-SIS) is proposed, which considers both the temporal ordering of group membership and the trust level of subject and security level of object. We also present its temporal logic specification. At last, a usage scenario is given to illustrate the practical application in subscription system.
