Abstract: Providing security mechanism such as authentication and confidentiality is a challenging issue in a publisher subscriber system due to loose coupling of publisher and subscriber. In this paper we present an approach to provide authentication, confidentiality in the publisher subscriber system. The authentication of publisher and subscriber as well as confidentiality of events is ensured by the use of pairing-based cryptographic mechanism such as cipher text policy attribute based encryption. The novelty of this work is that we use the layered encryption to increase the security with less overhead of key management. Here we have considered tree structure to maintain the subscriber requirements and each level in tree is considered as zone and different security level is provided for each zone.
