Secure Key Trade-off Protocols for Lateral Network File Systems

Abstract: Considering the problem of key establishment in many-to-many communication is crucial because of emerging trend in large scale distributed file system which supports parallel access to multiple storage devices. Existing current – internet standard uses Kerberos for establishing parallel session keys between storage devices and client, which has the following short comes (i) key exchange is facilitated by metadata server because of this reason it experiences heavy work load (ii) the previous session keys are not kept secured (iii) metadata server maintains information about session key, which leads to key escrow. The work focuses on addressing the above issues by providing a set of authenticated key exchange protocol and it has been shown that protocol are designed to reduce the workload on the metadata server and simultaneously supporting secrecy and free from key-escrow.
