Abstract

Authentication is one among a set of services that constitute a security subsystem in a modern computing or communications infrastructure. End User Authentication flexibility model proposed in this article will allow the user to have multiple authentications with varying levels of guarantee, and for suppliers to request and rely on mechanisms appropriate to the service requested. We describe the ticket used by clients, servers, model and algorithm to achieve authentication toward prevention of unauthorized access to in sourced data on applications level. An authentication to end-user proposed in this article is a simple three level ticket request model solution in an open distributed environment. We also develop an analytical password for the proposed mechanism and validate this approach through experiment. Furthermore, we explore this approach to end user authentication and demonstrate the conception of a textual password which in many cases improves the security. We analyze Deffie-Hellman exchange weakness and present how it can be made robust against attacks. Our approach is based on the use of the Kerberos authentication technique and the Diffie-Hellman Key exchange.
