Abstract: A smart card, in particular for pay-TV applications, has a microcontroller and a programmable-function hardware component that, together with the microcontroller, forms a unit. The function programming capability allows the crypto algorithm to be changed continuously, thus making it considerably more difficult, or impossible, to simulate the smart card. In one method, the smart card is used with a decoder for pay-TV transmitters. In this method, a control command is transmitted in the television signal and results in the reprogramming of the programmable-function hardware component.
