摘要

Smartcard is the most secure and cheap portable computing device today and became the world's highest-volume market for semiconductors in the year 2K. As smartcards become multi-application (by hosting a dedicated Java Virtual Machine) and more and more powerful (32 bit processor, more than 1MB of stable storage [Gem99]), the need for database management arises. Embedding database management (query processing, access rights, transaction control) in the card simplifies and makes application code smaller and safer. Smartcard DBMS cover the need of confidential, portable and sharable databases such as: (i) diplomatic, military or business data, (2) user profiles (passwords, cookies, bookmarks, licenses, agenda...), and (3) personal folders (scholastic, healthcare, loyalty...). However, smartcards have severe hardware limitations (tiny RAM, very costly write in stable storage...) making traditional database techniques irrelevant. Small footprint DBMS (e.g., Oracle 8i Lite), designed for portable computers and PDA, do not address the more severe limitations of smartcards. In a recent paper [BBP+00], we addressed this problem and proposed the design of what we call a PicoDBMS. Since then, we have implemented a full-fledged PicoDBMS prototype in JavaCard. We are porting it on Bull's 32 bit Smartcard, which we got only recently. Thus, the objective of the demonstration is to: 1. Validate our design by building a complex database application (with respect to the smartcard) on our prototype and showing the benefits of the approach. 2. Validate our techniques by showing that they match the smartcard hardware constraints.
