Security aware content-based publish/subscribe system

Improving information propagation in wide-area communication is an important concern of publish/subscribe systems especially for content-based systems. In secure domain, the dissemination of events in a large scale decreases the importance of the event. The issue of confidentiality appears when the plaintexts of events should be kept private from the infrastructure to counter against eavesdropping. Thus, the infrastructure must remain able to make correct routing decisions efficiently. Our goal is to ensure event delivery to consumers in case of malicious dispatchers without decreasing CBPS (content-based publish/subscribe) performances such as expressivity and scalability. This solution is based on smart cards as trusted devices. It uses certificate to enforce security during authentication stage. It is a generic solution applicable for all CBPS.
