Authenticated Key Exchange Protocols for Parallel Network File Systems
Abstract— Authenticated Key Exchange Protocols for Parallel Network File Systems. We study the problem of key establishment for secure many-to-many communications. The problem is inspired by the proliferation of large-scale distributed ﬁle systems supporting parallel access to multiple storage devices. Our 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. < Final Year Projects 2016 >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.
