Design and Performance Analysis of Queue-based Group Diffie-Hellman Protocol (QGDH)
Sunghyuck Hong, Sungjin Lee · KSII Transactions on Internet and Information Systems · 2013
Current group key agreement protocols, which are often tree-based, have unnecessary delays that are caused when members with low-performance computer systems join a group key computation process.These delays are caused by the computations necessary to balance a key tree after membership changes.An alternate approach to group key generation that reduces delays is the dynamic prioritizing mechanism of queue-based group key generation.We propose an efficient group key agreement protocol and present the results of performance evaluation tests of this protocol.The queue-based approach that we propose is scalable and requires less computational overhead than conventional tree-based protocols.
