Extending the data storage capabilities of a Java-based smartcard
C. H. Cap, Nico Maibaum, Lars Heyden · 2002
Present limitations on data memory for Java-based smartcards are a serious restriction for application development. The paper presents a method for enhancing the data memory using virtual memory. Transparency for the off-card application is achieved by the facade design pattern. Security constraints of smartcard applications have implications for the overall architecture and influence the proposed design. The architecture is used in the EU project FASME for storing a larger number of XML-based administrative documents on a JavaCard for electronic government purposes.
