摘要

Java Card technology enables smart cards and other devices with very limited memory to run small applications, called applets. It provides users with a secure and interoperable execution platform that can store and update multiple applications on a single device. This Java Card technology is now a mature and accepted standard smart card standards and SIM technology. However, the main concern of Java Card is now its low execution speed caused by the hardware limitation. In this paper, we propose several ideas about how to improve an execution speed of Java Card. The key idea of our approach is that an EEPROM writing operation is more expensive than that of RAM. We suggest how to use RAM as much as possible; Transaction_In_RAM(TrIR), Reso-lution_In_RAM and Java Object-buffer.
