Abstract

Smart card technology is relatively new but offers an economic and convenient solution to the problems of user-authentication. This paper discusses the requirements for user authentication and digital signature in complex networks and examines the problems of integrating a smart-card sub-system. It proposes some design approaches for providing a useful lifetime for a smart card and for handling the computations required for 512-bit RSA digital signatures.
