摘要
An integrated circuit embedded in a smart card has a rewritable non-volatile memory in which an instruction file is stored. A control logic circuit in the integrated circuit converts random data into authentication data by executing instructions read from the instruction file, preferably by controlling a simplified data processing circuit having a shift register, an exclusive-OR logic circuit, and specialized bit operation circuits. A card issuer issuing smart cards including this integrated circuit writes different instruction files in different smart cards, thereby enhancing the security of the smart cards.
