Cryptanalysis of an ID-based Authenticated Dynamic Group Key Agreement with Optimal Round
並列摘要
Recently, Teng, Wu and Tang proposed a new ID-based authenticated dynamic group key agreement (DGKA) protocol. They claimed that leaving users cannot calculate subsequent group session keys and joining users cannot calculate previous group session keys. In this paper, we will show that Teng et al.'s protocol cannot provide forward confidentiality or backward confidentiality.
