Abstract :
Smart cards have the tremendous advantage over their magnetic-stripe ancestors of being able to execute cryptographic algorithms in their internal circuitry. This means that the user´s secrets (be these PIN codes or keys) never have to leave the boundaries of the tamper-resistant silicon chip, which brings maximum security to the overall system in which the cards participate. Smart cards also provide special-purpose microcontrollers with built-in, self-programmable memory. Together, these features make the cost of a malevolent attack far greater than the benefits. in 1996, 600 million IC cards will be manufactured throughout the world. This article surveys the existing crypto-dedicated microprocessors and describes some of their possible evolutions
