Abstract

Content-Based Publish-Subscribe system is an important emerging model in e-commerce applications. The distribution of contents to the Subscribers in a scalable and secured way is a very important requirement of these applications. Security schemes exercising centralized control cannot be applied directly to these applications due to the increased number of Subscribers subscribing to a particular event. This is because of the enormous growth of Internet. The centralized approach increases the burden on the central controller, which is the major entity in security management. To solve this problem, an efficient grouping is done based on the decentralized mechanism and a novel key management scheme is proposed for secured distribution of contents. The proposed method minimizes the overheads. The model is simulated and the results are found to be optimum compared to other methods.
