Secure Event Dissemination in Publish-Subscribe Networks

Abstract. 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. There are two important challenges in building a secure and scalable content-based event dissemination infrastructure: (i) How to handle complex and flexible subscription models while preserving the efficiency and scalability of key management algorithms? (ii) How to securely route events on a pub-sub network while preserving the confidentiality of its attributes? In this paper, we describe the design and implementation of PSGuard, for se...
