Since 1998 Bull CP8 works on a smart card specifically dedicated to the Internet network. The basic idea is to consider that card is a network computer which is able to use the resources of the terminal to which it is connected (keyboard - screen - mouse - navigator - Internet access). Our goal is to transform a smart card into a true node of the Internet network; a card implements applications of the internet world (http, electronic mail). In shorts smart card is a web server, it can be accessed from a web browser, and is able to manage several TCP connections (as a client or a server), for example card will work like a security proxy.

A first generation of (Java) card internet has been developed. Our objective is to integrate these cards into the Internet community and to improve the security (authentication, integrity, and confidentiality) required by the new services provided by the network.

We enter in the era of the ubiquitous computing. What means that more and more objects integrate a microprocessor, and have the capacity to be connected to Internet (according to Frost & Sullivan 40 % of the devices connected to Internet in 2001 will not be personal computers). A user (sometimes a mobile one) will use several types of terminals connected to internet, for example

• A mobile phone, the GPRS network will give access to Internet from a GSM mobile in Europe in the early years 2000.
• A game console
• A TV set using a set top box
• An organizer
• A laptop

In this context, the internet card is used to authenticate a (mobile) user who uses an anonymous terminal. If necessary it manages the configuration of this terminal which is required for the setting of a particular service. This technology constitutes a revolution of the ergonomics of the card and its use through the Internet network.
