Key establishment is the main issue for secure many-to-many communications. We study the problem of large-scale distributed file system, which support parallel access to multiple storage devices. The existing Kerberos-based protocol has a number of limitations: scalability of the protocol is restricted, it provide less forward secrecy, and leads to key escrow. In this paper, we propose a variety of authenticated and encrypted key exchange protocols that are designed to address the above issues.

Compare to the existing Kerberos based protocols our proposed protocols are significantly reduce the workload of the metadata server and concurrently supporting forward secrecy and escrow-freeness.
