Implementation of Smartcard Using Multi Authentication Method

Abstract

With the rapid development of information and communication technology, online dissemination is rapidly increasing. So, protection of information has become important. Recently the authentication system using public key infrastructure (PKI) is being utilized as an information protection infrastructure for electronic business transactions. The smartcard system makes the most use of such an infrastructure. In addition, the smartcard has an excellent advantage in security and moving. However, because the certification based on the current PKI provides only basic user certification information, the use has to be limited in various application services that need the identification and authorization information as well as face-to-face information of the user. Therefore, our paper proposes a method for personal identification. The smartcard could be forged and altered. In order to protect a system from various kinds hackings and related treats, we have proposed angular and private key multiplexing for cut off of smartcard forgery and alteration based on a optical cryptosystem.
