Novel Efficient and secure protocol design to exchange information in network

Abstract

We study the issues of key creation for secure many-to-many communications. issue is impressed by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. Our work focuses on the current internet normal for such file systems, i.e., parallel Network file system (pNFS), that makes use of Kerberos to establish parallel session keys between senders and storage devices. Our review of the prevailing Kerberos-based protocol shows that it has variety of limitations: (i) a information server facilitating key exchange between the senders and also the storage devices has heavy work that restricts the quantifiability of the protocol; (ii) the protocol doesn't offer forward secrecy; (iii) the information server generates itself all the session keys that are used between the data owners and storage devices, and this inherently results in key escrow.
