Succinct role-based access controls for XML documents that combines queryable XML-aware compression with RBAC multi-encryption is a possible solution to provide the benefits of significant storage efficiency and security for important data. While the description of this proposal has been accepted as a potentially worthwhile solution for these common requirements in many organizations, to our knowledge no implementation and testing has been conducted to provide experimental results that can be used to verify the feasibility and validity of this proposal. The focus of this thesis was testing these novel ideas, utilizing a implementation combining XML-aware queryable compression techniques and multi-encryption enforcement of role-based access controls over XML documents. Detailed testing, analysis, and comparisons show that it is feasible to impose RBAC policies on large XML documents by utilizing the minimum number of encryption keys while achieving reasonable data compression goals and retaining the query enabled document structure.
