Java Card is a Java running environment tailored for smart cards. In such small systems, resources are limited, and keeping application size as small as possible is a first order is-sue. Dictionary compression is a promising technique taken into consideration by several authors. The main drawback of this technique is a degradation in the execution speed. In this paper, the authors propose combining the dictionary compression with another compression technique based on the folding mechanism; the latter is less effective in terms of space savings, but has the advantage of speeding up the execution.
