Reactive Key Management Scheme for Access Control in Group Communications
Hyeong‐Il Kim, Younho Lee, Youngho Park, HongYeon Yoon · IEICE Transactions on Communications · 2007
To control various access privileges in group-oriented applications having multiple data streams, we present a novel reactive key management scheme where each member can obtain the key of a data stream from public parameters only when necessary. Compared with the previous schemes, this scheme significantly reduces the amount of rekey messages for dynamic membership change due to its reactive nature.
