Title
Group Key Distribution in Computer Networks: GKD in Computer Networks,Used
Delivery time: 8-12 business days (International)
This book presents a new protocol for a scalable multicast key distribution protocol. The proposed protocol is based on Key Management using Boolean Function Minimization (KMBFM) technique. It is considered one of the best solutions proposed for solving the scalability of multicast security protocols depending on a centralized manager. Instead of using one tree as in KMBFM, the members are divided into a number of subgroup trees. The comparison of the proposed protocol with KMBFM protocol shows that the proposed protocol achieves a lower storage at both the group manager and the group members compared to KMBFM protocol. Also, it achieves a lower communication overhead in case of a single member leave and a comparable communication overhead in case of multiple leaves. Furthermore, the probability of conducting a successful collusion attack in the proposed protocol is less than that proposed in KMBFM protocol. This is due to the fact that, in the proposed protocol, each member knows less number of keys than in KMBFM protocol.
