Secure data management in decentralized systems presents a collection of essays, covering a wide range of todays active areas closely related to database security organized as follows. In Part I, We review classical work in database security, and report their recent advances and necessary extensions. In Part 11, We shift our focus to security of the Extensible Markup Language (XML) and other new data models. The need for cross-domain resource and information sharing dramatically changes the approaches to access control. In Part 111, we present the active work in distributed trust management, including rule-based policies, trust negotiation and security in peer-to-peer systems.
