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.

  • Solaris 10 End of Life
    Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

  • Support for Mobile Augmented and Synthesized Worlds
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Illinois Digital Environment for Access to Learning and Scholarship Repository Support for Mobile Augmented and Synthesized Worlds December 17, 2007 Won J. Jeon and Roy H. Campbell {wonjeon, rhc}@uiuc.edu Department of Computer Science University of Illinois at Urbana-Champaign Abstract Virtual worlds provide 3D-immersive experiences to users and some of them already have already launched commercial service to users. As computing environment becomes more heterogeneous, more mobile users are anticipated to access the virtual world with their mobile devices. However, still there are challenges and problems to be addressed for mobile users. In this report, state-of-art virtual world platforms are presented and their key features are compared. We compare possible approaches to tackle these problems to support virtual worlds for mobile devices. Transcoding scheme at the proxy is presented and evaluated for a given computing and networking environment. 1. Introduction A virtual world is a computer-simulated or synthesized environment where multiple users inhabit and interact to each other via avatars. The world mimics the real world via simulated real world physics and the persistence of the world comes from maintaining and updating the state of the world around the clock. Historically this concept is rooted from distributed interactive simulation (DIS) and massively multiplayer online role- playing game (MMORPG). DIS is used mainly by military organizations whereas MMORPG has gained huge popularity among general users or gamers. The world is typically represented as 2D or 3D graphics to multiple users.

After all, developers are a demanding audience. But the article received hundreds of comments on Reddit, Slashdot, Hacker News, and Twitter, and it inspired many letters to the editor. The piece even received happy social media posts from those who made the list, including the US National Security Agency and a.i. solutions. The US National Security Agency was secretly pleased we noticed its Ghidra binary decompilation tool. The team from a.i. solutions was happy its DSTE trajectory design tool made the list. The tenor of conversation was both positive and polite. That speaks volumes about the excellent character of Java developers, don’t you think? But, developers being who they are, opinions on what should have made the list abounded. The good news is, Java has transformed the world. The bad news is, my list didn’t represent enough of the world beyond the United States. For example, there’s the Java code written to manage the Brazilian Healthcare Information System and the Brazilian tax system (Duke’s Choice Award winner in 2005).

  • 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.
