The Application of Proxy Re-Cryptography in Group Key Management for Group Communications System

This paper presents a group key management mechanism PTGKM based on hierarchical and domain structure in Near-Space Network. The mechanism combines hierarchical and domain structure with the use of proxy re-cryptography algorithms. The Near-Space Network is a new space area which is about 20-100 kilometers and between aviation and spaceflight. There are potential applications for Communication Guarantee, Information Collection and Disaster Quickly Response and it has be a hot research field. The size of the Near-Space Network is very large, and resources are very limited. Group communication has been a very important application technology because of its ability to send data to a large number of users in the network in an efficient manner.
