ABSTRACT
This chapter aims to discuss an authentication mechanism for Future Internet architectures, a case study of an architecture is considered to compare the performance analysis with TCP/IP in the distributed environment. Authentication is a process of determining a user who they claim to be whereas biometric authentication is a process of recognizing the person using a digitized biological piece of the human. Threats involve attacks against the authentication protocols itself, and the attacks that reveal tokens or any sensitive information. The recognition of the smart card by the system is the first authentication and prompting for password is the second level to complete the process of authentication. The strength of the authentication derives the user access for an application along with what kind of authorization rights have been issued to that particular user. Cascaded authentication is the solution to a set of problems that have arisen from confederations of autonomous systems.
