Group Key Management in Grid Environment

Grid manages resources and services distributed across multiple control domains. Grid computing provides people the way to share large mount of distributed resources and services that belong to different local domain. It also makes security problems more complicate, such as in the grid group communication. In this paper, we analyze security requirements of grid environment, especially for the secure group communication. We discuss the group key management for group communication and propose the scheme to implement the flexible secure group key management in grid environment. The algorithm and protocol are presented according to different conditions, and their characteristics are analyzed
