The provisioning of basic security mechanism such as authentication and confidentiality in the publish/subscribe system. Authentication in this system is difficult to achieve due to the loose coupling between publishers and subscribers. Likewise, Confidentiality of events and subscriptions conflicts with content-based routing. To ensure authentication and confidentiality in broker less publish/subscribe system the authors adopt pairing based cryptography mechanism. Further, broadcasting encryption algorithm is adapted to provide subscription confidentiality by clustering subscribers according to their subscription by providing a private key with their credentials.
