We introduce a new payment architecture that limits the power of an attacker while providing the honest user with privacy. Our proposed method defends against all known attacks on the bank, implements revocable privacy, and results in an efficient scheme which is well-suited for smartcard-based payment schemes over the Internet.

The Java Card language is a trimmed down dialect of Java aimed at programming smart cards. Java Card specifies its own class file format (the Java Card Converted APplet (CAP) format) that is optimised with respect to the limited space resources of smart cards. This paper deals with the certified development of algorithms necessary for the conversion of ordinary Java class files into the CAP for...

Chip-Secured XML Access (C-SXA) is a versatile and tamper-resistant XML-based Access Right Controller embedded in a smart card. C-SXA can be used either to protect the privacy of onboard personal data or to control the flow of data extracted from an external source. Tamperresistance is inherited from the smart card for on-board data or achieved using cryptographic techniques for external data. ...

This paper introduces SmartPRO, a smart card based technology aiming at protecting content in professional workflows. It gives an overview on how SmartPRO works. It also explains the design constrains that led to the use of smart cards and some of the extra difficulties implied by this choice in order to get to an implementation that may be industrially deployed.

Based on some stylised fact, and using a proprietary database of more than 750 agreements spanning from collaborations to merger and acquisition agreements between 1997 and 2003, we try in this paper to characterise and understand the movement of industry concentration. We ask whether the smart card industry will know a monitoring oligopolistic concentration on the fundamental assets and market...

This paper considers the problem of finding a minimumweighted representation of an integer under any modified radix-r number system. Contrary to existing methods, the proposed transformation is carried out from the left to the right (i.e., from the most significant position). This feature finds numerous applications and especially in fast arithmetic techniques because it reduces both time and s...
