Extended Memory Card
Smartcard chips vendors have always done their best to embed more memory inside cards. These efforts are driven to allow their customers smartcard manufacturers to mask more software inside cards (in ROM) but, above all, to help them to provide cards with more memory dedicated to the application (EEPROM). Even if the geometry is getting smaller and smaller, some applications do not match with t...
متن کاملDetermining the Causes of AccuVote Optical Scan Voting Terminal Memory Card Failures
Optical scan (OS) voting systems play an increasing role in the United States elections, with over 40 states deploying such systems. The AccuVote optical scanners (AV-OS) manufactured by ES&S account for over 20% of all OS systems. OS systems typically use removable media (cards) to provide election-specific programming to the scanners and to convey precinct election results for central tabulat...
متن کاملA Persistent Memory Management in Java Card
EEPROM as persistent memory in smart card has some different features with other memories. It consists of the pages with a fixed size and has the characteristics due to them. It is more efficient to consider them and to handle EEPROM by page than to think of it as a seamless space and to deal with it as one large chunk. Because smart card is categorized as the device closely interactive with us...
متن کاملMemory Forensics of a Java Card Dump
Nowadays several papers have shown the ability to dump the EEPROM area of several Java Cards leading to the disclosure of already loaded applet and data structure of the card. Such a reverse engineering process is costly and prone to errors. Currently there are no tools available to help the process. We propose here an approach to find in the raw data obtained after a dump, the area containing ...
متن کاملExtended Secure Memory for a Java Card in the Context of the Java Card Grid project
The Java Card Grid platform is a project carried out at LaBRI, Laboratoire Bordelais de Recherche en Informatique. It consists in setting up a platform composed of a large number of smart cards connected together by USB hubs and driven by PCs. The Java Card readers are assembled in a wall mount rack and are organized in a cluster-like architecture. The goal of the Java Card Grid project is to p...
