ABSTRACT
This paper presents an action-based fine-grained access control mechanism for structured documents. Firstly, we define a describing model for structured documents and analyze the application scenarios. The describing model could support the permission management on chapters, pages, sections, words, and pictures of structured documents. Secondly, based on the action-based access control (ABAC) model, we propose a fine-grained control protocol for structured documents by introducing temporal state and environmental state. The protocol covering different stages from document creation, to permission specification and usage control are given by using the Z-notation. Finally, we give the implementation of our mechanism and make the comparisons between the existing methods and our mechanism. The result shows that our mechanism could provide the better solution of fine-grained access control for structured documents in complicated networks. Moreover, it is more flexible and practical.

Mentions: Let us make an assumption that a creator has created the resource called “Exercise 1” including the object O1 and object O2. O1 is the questions parts and O2 is the answers parts. User A could apply for permission to access in the classroom (network address: 172.16.66.5–172.16.66.90) and they can read O1 and O2 between 8:00 am and 10:00 am; otherwise, he can only read O1. If the user is out of the classroom, the accessing requirements are always illegal. Results of some experiments are shown in Figure 7. The four situations of the illegal time and legal network address, the legal time and illegal network address, the illegal time and network address, and the legal time and network address are shown in Figures 7(a), 7(b), 7(c), and 7(d), respectively.
