دانلود Survey on Security Methods in Publish/Subscribe System

Abstract

Publish/subscribe  (pub/sub)  system  is  an  emerging communication  paradigm  that  offers  efficient  and  decoupled information     dissemination     in     distributed     environments. Decoupling increases the privacy of each participant. Publishers generate the flow of information as publications and subscribers interests   may  be  expressed  as  subscriptions.  Basic  security mechanisms such as authentication and  confidentiality  is  highly challenging in a content  based  publish/subscribe  system. These work  focused  on  a  review  and  comparison  of  different  security methods that are existing.
