QFilter: rewriting insecure XML queries to secure ones using non-deterministic finite automata
2010
The VLDB journal
In this paper, we ask whether XML access control can be supported when underlying (XML or relational) storage system does not provide adequate security features and propose three alternative solutions -primitive, pre-processing, and post-processing. Toward that scenario, in particular, we advocate a scalable and effective pre-processing approach, called QFilter. QFilter is based on non-deterministic finite automata (NFA) and rewrites user's queries such that parts violating access control rules
