javacard technology enables smart cards and other devices with very limited memory to run small applications. It provides users with a secure and interoperable execution platform that can store and update multiple applications on a single device. However, a major difficulty with javacard is its low execution speed caused by hardware limitations. In this paper, we propose a novel scheme about how to improve the execution speed of javacard. The key idea of our approach is a buffer cache scheme that uses RAM instead of EEPROM to improve the execution speed of javacard. The proposed scheme reduces I/O count, especially EEPROM writing. Our scheme is based on the high locality of java card objects and the use of RAM that is several magnitude faster than EEPROM.
