We prove a tight lower bound for generic protocols for secure multicast key distribution where the messages sent by the group manager for rekeying the group are obtained by arbitra...

— Both broadcast encryption (BE) protocols and multicast key distribution (MKD) protocols try to solve the same problem of private group communication. For the first time, we dis...

In this paper, we describe a novel approach to scalable group re-keying for secure multicast. Our approach, which we call Kronos, is based upon the idea of periodic group re-keyin...

Perfect Secrecy can only be achieved in multicast groups by ciphering data sent to the group with a different key every time a member joins or leaves the group. A Key Server must ...
