Abstract :

 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. This paper presents a novel approach to provide confidentiality and authentication in a broker-less content-based publish/subscribe system. This paper, also include a model that the secure friend discovery process as a generalized privacy preserving interest and profile matching problem. We identify a new security threat arising from existing secure friend discovery protocols, coined as runaway attack, which can introduce a serious unfairness issue. Here adapted pailler’s encryption mechanisms to ensure that a particular subscriber can match their interests (hobbies) with the publisher. Based on the interest match they can send friends request each other. After accepting the friends request they become friends and can send images, videos, and messages. Also we can send hidden messages inside the video. To thwart this new threat, we introduce a novel blind vector transformation technique, which could hide the correlation between the original vector and transformed results. Based on this, we propose our privacy- preserving and fairness-aware interest and profile matching protocol, which allows one party to match its interest with the profile of another.
