1 INTRODUCTION 1. Introduction The idea of a single smart card to be used for multiple services has been around for years. Instead of using separate access devices for different services‚ a user can access multiple services from different service providers by a single smart card. For example‚ a user can use the same smart card to log on to a remote server system‚ enter a secure building‚ and perform a financial transaction. This kind of design frees people from carrying many cards‚

The study of Public-Key Cryptography Enabled Kerberos Authentication by Sufyan and Mayada (2011) attempt to extend the Kerberos authentication protocol standard to support public key cryptography. This is to eliminate some of the limitations in the standard Kerberos protocol which uses symmetric key cryptography. There are 3 extensions to add support of public-key cryptography at different stages of the Kerberos framework‚ which are PKINIT‚ PKCROSS and PKTAPP. Public-Key Cryptography for Initial

Bitcoin: A Peer-to-Peer Electronic Cash System Satoshi Nakamoto satoshin@gmx.com www.bitcoin.org Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution‚ but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer

And I agree with those perspectives. I think that the Arizona State University’s iCourse system is a good example of flexible working. In the iCourse system‚ students can choose where to watch the lecture and do their course work. Based on my experience‚ this is one
