Extended Memory Card

چکیده
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 the current memory limitations due to smartcard constraints making impossible for the chips to be more than just a few millimeter square. The goal of the Extended Memory Card project is to suggest an architecture in which smartcards can securely "contain" more data than their own memory allows it. The card acts as a key to access information stored outside of it.

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...
متن کاملExtending the Contention Scheduling Model of Routine Action Selection: The Wisconsin Card Sorting Task and Frontal Dysfunction
We extend a previously developed model of routine action selection by incorporating functional components to support behaviour in a simple non-routine task – sorting cards according to a rule that must be discovered by the subject. A minimal extension to the previous model, consisting of an activation-based working memory/inference system in which evidence is incorporated by simply exciting or ...
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...
