Cloud And Parallel Network File System Using Authenticated Key Exchange Protocols

Anupama T, Refeeda K

Already we studied the issues of key establishment for secure many-to-many communications. The main problem is inspired by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. The system work focuses on the current Internet standard for such file systems, i.e., parallel Network File System (pNFS), which makes use of Kerberos to establish parallel session keys between clients and storage devices. Our review of the existing Kerberos-based protocol shows that it has a number of limitations (i) a metadata server facilitating key exchange between the clients and the storage devices has heavy workload that restricts the scalability of the protocol, (ii) the protocol does not provide forward secrecy, (iii) the metadata server generates itself all the session keys that are used between the clients and storage devices, and this inherently leads to key escrow.. In this paper, we propose a variety of authenticated key exchange protocols that are designed to address the above issues. We show that our protocols are capable of reducing up to approximately 90 % of the workload of the metadata server and concurrently supporting forward secrecy and escrow-freeness. All this requires only a small fraction of increased computation overhead at the client.
