Abstract

Our work concerns bytecode compression on an embedded, tiny and safe environment, and more specifically JAVA CARDS. [2] and [4] propose a way to compress java card bytecode into a format executable in an ultra light embedded system, using macro-packing. Our implementation, improved with new specifical algorithms, allows a better compress rate (up to 32%). In a smart card having 32kB EEPROM, up to 10kB can be freed, it is enough to store some applets. The execution of macro-packed programs is very simple and the code overhead in the operating system and in the virtual machine is very small. Unfortunately, the compression process is not feasible in a tiny embedded system. We propose a distribution of the compression process called Compression-Carrying Code or simply CCC. This distribution maintains the Java Card 2.11 compatibility [11], and allows a trusted, just-in-time compression by the embedded bytecode loader.
