Privacy Enhancing Identity Based Publisher Subscriber System
Keywords:
content based, publisher/subscriber, broker-less, security, identity-based encryption, paired based cryptography, symmetric keyAbstract
The provisioning of basic security mechanisms such as authentication and confidentiality is highly challenging in a content based publish/subscribe system. Authentication of publishers and subscribers is difficult to achieve due to the loose coupling of publishers and subscribers. Confidentiality of events and subscriptions conflicts with content-based routing. Hence, new mechanisms are needed to route encrypted events to subscribers without knowing their subscriptions and to allow subscribers and publishers authenticate each other without knowing each other.Our approach allows subscribers to maintain credentials according to their subscriptions. This project is adapted by the pairing-based cryptography mechanisms and symmetric key generation. In over all approach, provides fine-grained key management and the cost for encryption, decryption, and routing is in the order of subscribed attributes. Finally, the evaluations show that providing security is affordable
