Smart Cards?

A smart card is a plasticcard that contains an

embedded integrated circuit

(IC) Examples:

Student Cards Credit Cards Cell Phone SIM/USIM Cards

What makes Smart Cards so smart?

Card with microprocessor capable of

Storing information

Processing information

Add authentication and secure access to information

This is what makes a smart card smart Stupid cards cannot do this

Whats in a Card?


6/33

Contact or Contact Less?

Contact smart cards work bycommunicating via physicalcontact between a cardreader and the smart card

Contact less smart cardscommunicate by means of aradio frequency signal, with atypical range of less than 2

feet


7/33

Typical Configuration

Memory CapacityRAM : 256 bytes to 4KB

ROM : 8KB to 64 KB

EEPROM: 8KB to 64KB

Microprocessor: 8-bit to 16-bit


8/33

Advanced Configuration

GIGAntIC combines the unrivaled security features of 3G SIM cards with

up to 256 MB

Strong cryptographic algorithms will protect the value chain of digital content

distributions Allowing operators to propose innovative high ARPU-generating services

Where is the Java?

2

A subsetof Java

no threads, no doubles,garbage collector optional ...

With some extras

persistentand transient objects

transaction mechanism

And increased language-level security

standard sandbox (cf. web-browsers)

plus firewall between applets
