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.

fig1: The nesting relationship between objects.

Mentions: Function ∂ (∂:So → So) denotes the nesting relationship between objects. If o1, o2 ∈ So and ∂(o1) = o2, then o1 is nested by o2. Assuming object ok is included by document d and the object nested by ok is represented as ok−l, l is the nesting depth of ok in d when ok−l = d. So let ∂l = (∂)l; then ∂(ok) = ok−l, (∂(ok))2 = ∂(∂(ok)) = ok−2, …, and (∂(ok))l = ∂(…∂(ok)) = ok−l. The nesting relationship of objects, subdocuments, and documents could be described by multibranches tree. The structured document is the root of the tree, and the nested objects and subdocuments are nodes or leaves. For instance, in Figure 1, (∂(o111))l = or, l = 3. A sensible design of nesting depth could make the fine-grained access control more effective.
