An identity-based conference key distribution protocol based on SBIBD was proposed by Chung et al. in 2002 . However, this protocol suffers several problems. Consequently, participants cannot correctly authenticate one another and cannot calculate the same conference key. This study investigates these problems and proposes an improved protocol also based on SBIBD.
