Smart Card Research Perspectives Jean-Jacques Vandewalle Gemplus Systems Research Labs La Vigie, Z.I. Ath´elia IV, 13705 La Ciotat cedex, France [email protected] Abstract. This short paper introduces the issues and challenges of next genera- tion Java-based smart card platforms. Betting on a continuous evolution toward open computing devices, next generation cards will consist in embedded Java micro-server platforms. Those platforms will be able to serve various types of services and applications thanks to two important system features: adaptability and maintainability. Two features that have to be carefully taken into account in the research perspectives described in this paper: real Java for cards, cards inte- gration in a networked world, and flexible and adaptable cards. 1 Introduction The research perspectives described in this paper leverage the vision of generic, adaptable, and maintainable smart cards that will meet the re- quirements of both the adjustment of smart card systems to the environ- ment and the persistence of smart card applications in an evolving en- vironment. The technology used to implement these smart card systems blur classical boundaries such as those between distributed and embed- ded systems, those between low- and high-end card platforms, or those between pre- and post-issuance (the term ”post- issuance” describe the ability for smart cards to host and to run applications after they have been issued [1]). Thus, the goal of research perspectives is to bring some consistency to the possible solutions to these issues. The emergence of powerful and personal services supported by multi- purpose devices has the potential to dramatically enrich the range of ap- plications that smart cards will be able to serve. With the right platform and infrastructure in place, these smart cards will radically leverage card This paper is an author’s reviewed version of a previous paper. This revision is for the only purpose of accompanying the author’s invited talk to the CASSIS 2004 conference. The previ- ous paper by Jean-Jacques Vandewalle and Gilles Grimaud has been published (but couldn’t be presented) in the proceedings of the Smart Objects Conference (SOC’2003), Grenoble, 15-17 May 2003.

businesses as they enable card makers to offer to their customers solu- tions to implement and deliver complex and flexible business services. In consequence, the second goal of these research perspective is to par- ticipate in the understanding of this new possibilities by explaining and describing the research topics and their challenges. This paper is organized as follows. Research perspectives are pre- sented within the following three categories: ”Real Java for smart cards”; this category reminds the central place of Java in smart cards, the Java limitations of the current Java Card 2.x specifications, and the will to provide a new ground-breaking release for next generation Java-based smart card;
