A Detailed Study on Public Key Cryptographic Primitives for Securing Publish/Subscribe Systems.

The publish/subscribe (pub/sub) system is one of the most promising communication paradigm for integration of information systems. It is difficult to provide security mechanisms like authenticity and confidentiality in content based publish/subscribe system. Authenticity is hard to achieve in pub/sub system due to one of its characteristics, de-coupling in time between publishers and subscribers. Furthermore, traditional mechanisms used for encrypting whole message and thus provide confidentiality conflicts with content based routing paradigm. This paper investigates the merits and possibility of different types of public key cryptographic primitives for pro-viding security to publish/subscribe systems. Hence we perform detailed study on different types of public key cryptographic primitives.
