Since the early eighties IFIP/Sec has been an important rendezvous for Information Technology researchers and specialists involved in all aspects of IT security. The explosive growth of the Web is now faced with the formidable challenge of providing trusted information. IFIP/Sec'01 is the first of this decade (and century) and it will be devoted to "Trusted Information - the New Decade Challenge" This proceedings are divided in eleven parts related to the conference program. Session are dedicated to technologies: Security Protocols, Smart Card, Network Security and Intrusion Detection, Trusted Platforms. Others sessions are devoted to application like eSociety, TTP Management and PKI, Secure Workflow Environment, Secure Group Communications, and on the deployment of applications: Risk Management, Security Policies andTrusted System Design and Management. The year 2001 is a double anniversary. First, fifteen years ago, the first IFIP/Sec was held in France (IFIP/Sec'86, Monte-Carlo) and 2001 is also the anniversary of smart card technology. Smart cards emerged some twenty years ago as an innovation and have now become pervasive information devices used for highly distributed secure applications. These cards let millions of people carry a highly secure device that can represent them on a variety of networks. To conclude, we hope that the rich "menu" of conference papers for this IFIP/Sec conference will provide valuable insights and encourage specialists to pursue their work in trusted information.

In the Information Society, the smart card, or smart device with its processing power and link to its owner, will be the potential human representation or delegate in Ambient Intelligence (Pervasive Computing), where every appliance or computer will be connected, and where control and trust of the personal environment will be the next decade challenge. Smart card research is of increasing importance as the need for information security grows rapidly. Smart cards will play a very large role in ID management in secure systems. In many computer science areas, smart cards introduce new dimensions and opportunities. Disciplines like hardware design, operating systems, modeling systems, cryptography and distributed systems find new areas of applications or issues; smart cards also create new challenges for these domains. CARDIS, the IFIP Conference on Smart Card Research and Advanced Applications, gathers researchers and technologists who are focused in all aspects of the design, development, deployment, validation and application of smart cards or smart personal devices.This volume contains the 20 papers that have been selected by the CARDIS Program Committee for presentation at the 6th International Conference on Smart Card Research and Advanced Applications (CARDIS 2004), which was held in conjunction with the IFIP 18th World Computer Congress in Toulouse, France in August 2004 and sponsored by the International Federation for Information Processing (IFIP). With 20% of the papers coming from Asia, 20% from America, and 60% from Europe, the competition was particularly severe this year, with only 20 papers selected out of 45 very good submissions. Smart Card Research and Advanced Applications VI presents the latest advances in smart card research and applications, and will be essential reading for developers of smart cards and smart card applications, as well as for computer science researchers in computer architecture, computer security, and cryptography.
