SMART CARD USING AUXILIARY PROCESSOR

摘要

PURPOSE: A smart card is provided to improve performance such as a process speed using an auxiliary processor in order to execute byte code and support the execution. CONSTITUTION: A storing unit(301) stores programs and data. An encryption unit(303) performs encryption for protecting the programs and data. An input/output unit(370) transmits the data encrypted by the encryption unit(303) to the outside, and receives data from the outside. An auxiliary processor(310) performs a Java card byte code function. A CPU(302) controls an entire smart card system and performs a desired operation.
