In a federated information system with diverse participants (from different organizations) such as data producers, data consumers, or both, the need of cross-organizational information sharing naturally arises. However, different types of applications often need different forms of information sharing. In particular, while some applications (e.g., stock price updating) would need a publish-subscribe framework, the on-demand information access is more suitable for other applications. A number of information brokering systems have been developed to provide efficient and secure information sharing. Many existing information brokering systems adopt server side access control deployment and honest assumptions on brokers.
