Abstract:

Java card is a new kind of smart card based on the Java language. An applet executing on a Java card faces the scarce memory resources and the fixed e  xecution time constraints. For this reason, it is very essential to optimize the cap file that is loaded to the card. A design of the Java card bytecode optimize based on redefined instructions and basic-block compression is put forward in this paper. We can obtain the bytecode files which have a smalle r size, and a minimal execution time penalty.

Key words: smart card;Java card, bytecode, optimization, bytecode compression
