Secure Content Sharing using Third Party with Broadcast Encryption for Stateless Receivers
In this paper we deal with the problem of an owner sending a message to a group of users such that some subset of users is considered revoked and should not be able to obtain the content of the message. We concentrate on the stateless receiver case, where the users do not update their state from session to session. Many broadcast encryption protocols require handshaking for the contents sharing. In this paper, we propose architecture for secure contents sharing using a un trusted third party with out using any handshaking. The main improvements of using the third party are: (1) content owner need not be on-line all the time and (2) the storage space is limited in the content owner.
