This book covers several topics that are substantially different from programming models found in earlier versions of the Java Card platform and is not meant to comprehensively introduce or cover general programming topics. The Java Card 3 Platform currently includes releases 3.0 and 3.0.1. The Java Card 3 Platform consists of two editions, both of which are backward compatible with previous versions and share key security features. This book is strictly for use with the Classic APIs, which appear in both editions. ■ Classic Edition - Targets more resource-constrained devices that support applet- based applications and contains only Classic APIs. The Classic Edition is based on an evolution of the Java Card Platform, Version 2.2.2. ■ Connected Edition - Features a significantly enhanced runtime environment and a new virtual machine. It includes new network-oriented features, such as support for web applications, including the Java™ Servlet APIs. The Connected Edition supports the Classic APIs, but also supports applets with extended and advanced capabilities. Java Card™ technology combines a subset of the Java™ programming language with a runtime environment optimized for smart cards and similar small-memory embedded devices. The goal of Java Card technology is to bring many of the benefits of the Java programming language to the resource-constrained world of smart cards. The Java Card API is compatible with international standards such as ISO7816 and industry-specific standards such as Europay, Master Card, Visa (EMV). vii Who Should Use This Book This book is for applet developers using the Application Programming Interface for the Java Card Platform, Version 3.0.1, Classic Edition to implement applet management, multiselectable applets, logical channels, Remote Method Invocation (RMI), and extended APDUs for the Java Card platform. This book is also for developers who are considering creating a vendor-specific framework based on version 3.0.1 of the Java Card technology specifications, Classic Edition. Before You Read This Book Before reading this guide, become familiar with the Java programming language, object-oriented design, the Java Card technology specifications, and smart card technology. A good resource for becoming familiar with Java and Java Card technology is the Sun Microsystems, Inc. web site, located at http://java.sun.com.

Abstract: Many publications have studied the various issues concerning Java Cards security regarding software and/or hardware attacks. However, it is surprising to notice that the particular case of exception-related mechanisms has not been tackled yet in the literature. In this article, we fill this gap by proposing several attacks against Java Card platforms based on both exception handling and exception throwing. In addition, this study allows us to point out that a weakness known by the web-oriented Java community for more than a decade still passes the different steps of the state-of-the-art Java Card application deployment process (namely conversion and verification). This appears all the more important as the Java Card 3 Connected Edition specifications have started to bridge the gap between the two worlds that are Java Cards and Java web services. 1 INTRODUCTION that no pointer arithmetic is used in a Java Card ap- plication and that objects behave according to a given The Java Card technology is, as of today, the world’s contract defined by their Java class, superclasses and leading technology in the smart card field.

  • 1 Introduction
    User Customization of Virtual Network Interfaces with U-Net/SLE David Opp enheimer and Matt Welsh fdavidopp,[email protected] Decemb er 9, 1997 Abstract We describ e U-Net/SLE Safe Language Extensions, a user-level network interface architecture which enables p er-application customization of communication semantics through downloading of user extension applets, imple- mented as Java class les, into the network interface. This architecture p ermits application s to safely sp ecify co de to b e executed within the NI on message transmission and reception. By leveraging the existing U-Net mo del, applications may implement proto col co de at the user level, within the NI, or using some combination of the two. Our current implementation, using the Myricom Myrinet interface and a small Java Virtual Machine subset, obtains go o d p erformance, allowing host communication overhead to b e reduced and improving the overlap of communication and computation during proto col pro cessing. 1 Intro duction Recentwork in high-sp eed interconnects for distributed and parallel computing architectures, particularly workstation clusters, has fo cused on developmentofnetwork interfaces enabling low-latency and high-bandwidth communication. Often, these systems bypass the op erating system kernel to achieve high p erformance; however the features and functionality provided by these di erent systems vary widely. Several systems, such as U-Net [26] and Active Messages [27], virtualize the network interface to provide multiple applications on the same host with direct, protected network access. Other systems, including Fast Messages [16] and BIP [17], eschew sharing the network in lieu of design simplicity and high p erformance.

  • Fully Verified JAVA CARD API Reference Implementation
    Fully Verified JAVA CARD API Reference Implementation Wojciech Mostowski Computing Science Department, Radboud University Nijmegen, the Netherlands [email protected] Abstract. We present a formally verified reference implementation of the JAVA CARD API. This case study has been developed with the KeY verification system. The KeY system allows us to symbolically execute the JAVA source code of the API in the KeY verification environment and, in turn, prove correctness of the implementation w.r.t. formal specification we developed along the way. The resulting formal API framework (the implementation and the specification) can be used to prove correctness of any JAVA CARD applet code. As a side effect, this case study also serves as a benchmark for the KeY system. It shows that a code base of such size can be feasibly verified, and that KeY indeed covers all of the JAVA CARD language specification. 1 Introduction We present a formally verified reference implementation of the JAVA CARD API version 2.2.1 [11]. JAVA CARD is a technology used to program smart cards and it comprises a subset of the desktop JAVA; a subset of the programming language itself, and a cut down version of the API. Reference implementations of the API that are normally available for JAVA CARD are developed for a particular running environment, usually a JAVA CARD simulator or emulator. Some of the API rou- tines are not implementable in JAVA alone. For example, JAVA CARD transaction mechanism functionality is normally provided by the JAVA CARD VM and/or the operating system of the actual smart card hardware.

  • Information Foraging in Debugging
    AN ABSTRACT OF THE DISSERTATION OF Joseph Lawrance for the degree of Doctor of Philosophy in Computer Science presented on June 12, 2009. Title: Information Foraging in Debugging. Abstract approved: __________________________________________ Margaret M. Burnett Programmers spend a substantial fraction of their debugging time by navigating through source code, yet little is known about how programmers navigate. With the continuing growth in size and complexity of software, this fraction of time is likely to increase, which presents challenges to those seeking both to understand and address the needs of programmers during debugging. Therefore, we investigated the applicability a theory from another domain, namely information foraging theory, to the problem of programmers’ navigation during software maintenance. The goal was to determine the theory’s ability to provide a foundational understanding that could inform future tool builders aiming to support programmer navigation. To perform this investigation, we first defined constructs and propositions for a new variant of information foraging theory for software maintenance. We then operationalized the constructs in different ways and built three executable models to allow for empirical investigation. We developed a simple information-scent-only model of navigation, a more advanced model of programmer navigation, named Programmer Flow by Information Scent (PFIS), which accounts for the topological structure of source code, and PFIS 2, a refinement of PFIS that maintains an up-to- date model of source code on the fly and models information scent even in the absence of explicit information about stated goals. We then used the models in three empirical studies to evaluate the applicability of information foraging theory to this domain.

  • Performance Issues of Selective Disclosure and Blinded Issuing Protocols on Java Card
    Performance issues of Selective Disclosure and Blinded Issuing Protocols on Java Card Hendrik Tews⋆ and Bart Jacobs Digital Security Group, Radboud Universiteit Nijmegen, The Netherlands http://www.cs.ru.nl/{~tews,~bart} Abstract. In this paper we report on the performance of the RSA vari- ants of Brands protocols for zero-knowledge proof and restrictive blinded issuing [1]. The performance is relatively bad: For 4 attributes and an RSA key size of 1280 bits, blinded issuing takes about 10 seconds and the zero-knowledge proof takes about 9 seconds. For 2 attributes the zero-knowledge proof drops to 5 seconds. The poor performance comes from the fact that the cryptographic coprocessor on the Java card can only be employed in very limited ways. With appropriate support of the cryptographic coprocessor both protocols would run much faster. Key words: Java Card · selective disclosure · blinded issuing · perfor- mance 1 Introduction This paper has a (partly) negative message: it shows that certain desirable things cannot be done, . currently. In particular, it shows, via various performance measurements, that the current generation of Java cards is unsuitable for ad- vanced cryptographic protocols, such as privacy-friendly selective disclosure of attributes, via zero-knowledge proofs. The simple reason is that current cards are too slow. The more subtle reason is that the Java-Card API does not permit access to the (fast!) cryptographic primitive operations on the cryptographic co- processor. The hope that a clear exposition of this problem will contribute to a solution in the near future is an important motivation for writing this paper.
