A Survey on Authenticated Key Exchange Protocols Used for Accessing Storage Devices in Parallel Network File System

Key generation for secure many to many communications is a major problem addressed in accessing storage devices in parallel Network File System (pNFS). It use Kerberos to establish parallel session keys between client and storage devices By reviewing Kerberos based protocol it has been find that there are a number of limitations such as unscalable, lack of forward secrecy and key escrow. In this work I propose an authenticated key exchange protocol that is designed to address the above limitations of Kerberos. It can be show that this protocol will reduce the workload of server thereby achieving forward secrecy and the key become escrow free.
