Resist Dictionary Attacks Using Password Based Protocols For Authenticated Key Exchange

摘要

A parallel file system is a type of distributed file system that distributes file data across multiple servers and provides for concurrent access by multiple tasks of a parallel application. In many to many communications or multiple tasks, key establishments are a major problem in parallel file system. So we propose a variety of authenticated key exchange protocols that are designed to address the above issue. In this paper, we also study the password-based protocols for authenticated key exchange (AKE) to resist dictionary attacks. Password-based protocols for authenticated key exchange (AKE) are designed to work to resist the use of passwords drawn from a space so small that attacker might well specify, off line, all possible passwords. While many such protocols have been suggested, the elemental theory has been lagging. We commence by interpreting a model for this problem, to approach password guessing, forward secrecy, server compromise, and loss of session keys.
