<P>PROBLEM TO BE SOLVED: To prevent content of communication data from being known without concealing communication procedure. <P>SOLUTION: The information processor has a first information processing module and a second information processing module connected to each other by a signal line. The first information processing module transmits a clock signal to the signal line, superimposes a data signal on a rising edge of the clock signal, and superimposes an acknowledgement signal to the data signal received via the signal line on a falling edge of the clock signal. The second information processing module superimposes the data signal on the rising edge of the clock signal to be transmitted to the signal line by the first information processing module, and superimposes the acknowledgement signal to the data signal received via the signal line on the falling edge of the clock signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
