Maintenance of Topology in Publish/Subscribe Systems

In this paper we present a protocol for maintaining topology of single tree associated with numeric attributes. In content based publish/subscribe system it is very difficult to provide security to the events and subscriptions. The main concept here is to share data on any distributed systems. Here we provide idea of identity based encryption, provision to attempt authentication, confidentiality and scalability and it also provide pairing based cryptography to maintain security for the publisher and subscriber even if there is a loose coupling between publishers and subscribers.
