A New Scheme of Group Key Management Based on IPv6 Multicast

Multicast protocol is a mechanism to send a message to multiple receivers simultaneously.But the security of multicast hinders the wider application of multicast,of which the most important problem is key management.But most of current schemes of key management have problems such as long delay,poor scalability,poor reliability.According to features of multicast address of IPv6 and MLD protocol,a novel distributed multicast key management scheme of pattern logical key tree based on IPv6 and limited members is proposed in the paper.The result of simulation shows that the scheme has the advantages of short delay,rich scalability and rich reliability.
