Abstract Traditionally, research in secure group key agreement focuses on min-
imizing the computational overhead for cryptographic operations, and
minimizing the communication overhead and the number of protocol
rounds is of secondary concern.
The dramatic increase in computation power that we witnessed dur-
ing the past years exposed network delay in WANs as the primary culprit
for a negative performance impact on key agreement protocols.
