LockX: A System for Efficiently Querying Secure XML

Summary: LockX implements a multi-level access-control model for XML, where a DTD annotates elements with must/may/cannot security levels and unspecified levels inherit from the parent. Given a user level, LockX rewrites queries with efficient algorithms (per [1]) to guarantee safe evaluation, claiming to be the first prototype for efficient and secure XML querying.
