Mutual Authentication in the multi server environment of an organization, done at the transport layer, becomes complex when communication is done over the public link. Secure Shell protocol is the de facto standard and is deployed over the public network, for determining identity of client and server through Password-based key exchange schemes like AuthA and DH-EKE etc. This password based key exchange schemes and their multiple modes of operation are secure under the computational Diffie-Hellman intractability assumption but could not withstand security requirements and are vulnerable to attacks. So the paper focuses on additional tier of security for transport layer security protocol by using Fingerprint for mutual authentication in the multi server environment of an organization along with the Password. With the help of two identity parameters password and fingerprint, an ideal password authentication scheme would be generated. In this paper RNA-FINNT a new fingerprint hash algorithm would be implemented in the ideal password authentication scheme for generating a proof of fortification of transport layer security protocol. This could withstand security requirements and is not vulnerable to attacks. Paper generates a proof that if mutual authentication in the multi server environment of an organization is done with ideal password authentication scheme than intruders could not practice Phishing, IP or Server Spoofing etc and it would result in fortification of transport layer security protocol.
