Secure Publisher Subscriber System Using IBE

Abstract

In Today's life providing Security such as Authentication and Confidentiality are most demanding security issues. Improvement of basic security mechanisms like authentication, reliability and confidentiality is extremely difficult during a content based publish/subscribe system. This Paper presents a new way to provide confidentiality and authentications in a broker-less content-based publish subscribe system. The authentication of users is done using pairing based cryptography. Confidentiality of message is also ensured, by adapting the pairing-based cryptography mechanisms. In Identity Based Encryption, any unique and valid string which is distinctively identifies a user can be public key of the user. A key server maintains public and private master keys. Public key of each user is known to all users of system. The master public key can be used by the publisher to encrypt and send messages to a subscriber with any identity, for example an email address. To decrypt the message subscriber request a private key from server. Using master private key subscriber decrypt message successfully. On the whole approach provides fine-grained key management. Published events are routed to their subsequent subscribers. The assessment of this System provides security respect to authentication and confidentiality of event distribution.
