Popis: A group key management is essential scheme guaranteeing data confidentiality in multicast. To provide the strict secrecy in group communication, the rekeying delay has to be minimized. In this paper, we propose a new group key management protocol, called 'Proactive Key Management (PKM)'. We classify the key updating processes into 5 processes in operation order of key updating. By performing 2 key updating process before next rekeying start, PKM can remarkably reduce the rekeying delay. Specifically, we show through simulation result that by applying PKM, the rekeying delay can be reduced up to 80%.
