Abstract

Abstract

A novel constant-round authenticated group key agreement(AGKA) protocol was proposed to overcome the weakness of the existing common AGKA protocols.The proposed protocol combines the dual exponential challenge-response(DCR) signature and BD structure.It can resist the leakage of ephemeral secret DH exponent attack while retaining the security of the relative AGKA protocols,and is more efficient in terms of both communication and computation.
