Content-based publish-subscribe (pub-sub) systems are an emerging paradigm for building large-scale information delivery systems. Secure event dissemination in a pub-sub network refers to secure distribution of events to clients subscribing to those events without revealing the secret attributes in the event to the unauthorized subscribers and the routing nodes in a pub-sub network. A common solution to provide confidentiality guarantees for the secret attributes in an event is to encrypt so that only authorized subscribers can read them.
