An Efficient Password Security of Key Exchange Protocol based on ECDLP

Jayaprakash Kar and Banshidhar Majhi

Abstract

In this paper we have proposed an efficient password security of Three-Party and Multiparty Key Exchange Protocol based on Elliptic Curve Discrete Logarithm Problem. In three party Key exchange protocols allow two clients with a trusted Server where they registered their password and communicate over a public network to establish a common secret key called session key. Similary multiparty key exchange protocol allow a group of parties communicating over a public network to establish the session key. Due to their significance by in building a secure communication channel, a number of key exchange protocols have been suggested over the years for a variety of settings.Here we have taken two one-way hash functions to built the level of security high.

Note: Apropos to the following editer's suggession, I would like to inform you that I have merged the two papers 2009/316 and xxxx/540 and changed the title as "An Efficient Password Security of Key Exchange Protocol based on ECDLP". In this menuscript we have prposed both the protocols for the three party and multiparty and almost all remaining sections are same. Thanks & Regards Yours faithfully Jayapraksh Kar Editor's message: Dear Authors, I think that for your benefit of having a more influencial and important paper you should merge this result with the paper 2009/316. Having two papers which intersect (are identical) on all but 3 pages is not a wise move. the editors.
