A protocol for secure communication between set-top box and smart card in conditional access system is proposed. The proposed protocol uses the Schnorr identification scheme to achieve the authentication of smart card to settop box and uses an asymmetric cryptosystem to achieve the authentication of set-top box to smart card. Both security and performance of the proposed protocol are analyzed a...

The authentication of users in distributed systems poses special problems because users lack the ability to encrypt and decrypt. The same problems arise when users wish to delegate some of their authority to nodes, after mutual authentication. In most systems today, the user is forced to trust the node he wants to use. In a more satisfactory design, the user carries a smart-card with suucient c...

Password-based authentications using smart cards are very necessary between login users and a remote server. Smart card security breach threatens the security of password-based authentication schemes with smart cards. A password-based authentication scheme with smart cards against smart card security breach was proposed by C.T. Li et al. recently. However, it is noted that Li et al.'s scheme ne...

The use of certificates for secure transactions in smart cards requires the existence of a secure and efficient revocation protocol residing on the card. There are a number of existing protocols for online certificate validation, among which OCSP and SCVP are the most widely used. However there are not any real applications testing the efficiency of these protocols when run in a smart card, eve...

The smart card based authentication schemes are designed and developed to ensure secure and authorized communication between remote user and the server. In recent times, many smart card based authentication schemes for the telecare medical information systems (TMIS) have been presented. In this article, we briefly discuss some of the recently published smart card based authentication schemes fo...

A smart card runtime environment must provide the proper transaction support for the reliable update of data, especially on multiapplication cards like the Java Card. The transaction mechanism must meet the demands by the applications and the system itself within the minimal resources offered by current smart card hardware. This paper presents the current transaction model implied by the Java C...

The established legal value of digital signatures and the growing availability of identity-based digital services are progressively extending the use of smart cards to all citizens, opening new challenging scenarios. Among them, motivated by concrete applications, secure and practical delegation of digital signatures is becoming more and more critical. Unfortunately, secure delegation systems p...

This research paper describes the automated toll collection system for tollgate based on SMART card technology. Most of the toll collection system is in manual transaction. Nowadays, there is a huge rush in toll plaza in order to pay the toll tax. It results in traffic jam, fuel waste and time waste. The objective of this paper is to transform manual transaction to automated toll collection sys...

The demand for multi-application smart card platform has been increasing in various business sectors recently. When it comes to the actual implementation of the platform, however, network-based dynamic downloading in a Card Issuer-Service Provider separated environment has not made much progress. This paper introduces the smart card information sharing platform that uses licensing/policy/profil...

The Java Card technology has progressed to the point of running web servers and web clients on a smart card. Yet concrete deployments of multi-applications smart cards have remained extremely rare because the business model of the asynchronous download and update of applications by different parties requires the control of interactions among possible applications after the card has been fielded...
