HIGH SPEED SIGNAL PROCESSING SMART CARD

摘要

AN ACCESS CONTROL SYSTEM FOR SIGNAL PROCESSING APPLICATIONS INCLUDES AN INTEGRATED CIRCUIT (IC) (181) CARD, OR "SMART" CARD,THAT PROVIDES BOTH SECURITY CONTROL DATA DESCRAMBLING FUNCTIONS. A SECURITY CONTROL PROCESSOR IN THE SMART CARD (180) IC PERFORMS FUNCTIONS SUCH AS ENTITLEMENT MANAGEMENT AND KEY GENERATION.THE SMART CARD IC ALSO INCLUDES A DESCRAMBLER (130) FOR PROCESSING DATA,SUCH AS VIDEO DATA, AT HIGH DATA RATES.MECHANICAL CHARACTERISTICS OF THE SMART CARD SATISFY THE ISO STANDARD 7816-1.IN ADDITION, THE INTERFACE (187) TO THE SMART CARD (180) IS VIA EIGHT-TERMINALS ARRANGED ON THE SURFACE OF THE CARD IN ACCORDANCE WITH ISO STANDARD 7816-2.THE EIGHT TERMINAL INTERFACE (187) PROVIDES BOTH HIGH SPEED DATA I/O (INPUT AND OUTPUT) REQUIRED FOR DATA DESCRAMBLING AND ISO STANDARD LOW SPEED SERIAL DATA I/O.(FIGURE 1)
