PAC-RMPN: Password Authentication Code Based RMPN

Password authentication code (PAC) is a very important issue in many applications such as web-sites and data base systems etc. In this paper, PAC between two users to confirm authentication between them has presented. This research presents a novel solution to the era long problem password authentication at incoming level. A legitimate user typing his password only and press enter to propagate it to another user which he wants to be authenticated. My solution does not require the password (input code) to be hidden from anyone for security reasons. PAC-RMPN uses routing in message passing networks method (RMPN) which determines the positions of bits which sent to reach the destination. My method regenerates a new code each authentication process based RMPN that is convincingly more secure against both online and offline attacks. This scheme has some advantages such as secrecy of session key, and password privacy. This method proves the users authenticated does not need to hide passwords.
