In a communication network in which data for transmission to a receiver terminal is multiplexed on a time-division basis and scrambled, a communication control apparatus and method for allowing the data to be descrambled at the receiver without fail. A scrambler (1) of the sender apparatus includes a time-division frame monitoring circuit (12) for receiving an unscrambled data stream generated by multiplexing time-division frames for application data and relevant information for transmission to thereby extract information concerning a scramble key, a scramble key manager (15) for managing information concerning the scramble keys, an application data encryption processor (14) for acquiring a scramble key corresponding to the information concerning the scramble key as received from the time-division frame monitoring circuit (12) to thereby scramble the desired time-division frames of the data for transmission by using the scramble key as acquired. <IMAGE> |
