Efficient mutual authentication of server and client

Abstract

Password based authentication is one of the common forms of authentication used in practice. However, when a user/client device enrolls with a server using password information, the authentication process exposes hash of password information to the server which is prone to various types of passwords guessing attacks. Present disclosure provides a system and a method that authenticates a user without revealing his/her password information to a third-party identity provider. This is done by using bilinear parings to authenticate user without sending password information to the server and by way generating client shared secret, server secret, public key, private key and the like. This eliminates the need for storing any keys on multiple devices/third parties or storing password information on the server side.
