An input receiving section 102 of a transmitter apparatus 101 receives inputs of multiple synchronized signals r<SUB>1</SUB>, . . . , r<SUB>N</SUB>, an asynchronizing section 103 outputs multiple asynchronized signals v<SUB>1</SUB>, . . . , v<SUB>N </SUB>that are obtained by delaying the multiple synchronized signals r<SUB>1</SUB>, . . . , r<SUB>N </SUB>by time t<SUB>1</SUB>, . . . , t<SUB>N</SUB>, a modulating section 104 modulates the multiple output asynchronized signals v<SUB>1</SUB>, . . . , v<SUB>N </SUB>to output modulated signal w<SUB>1</SUB>, . . . w<SUB>L </SUB>(1<=L<=N), a transmitting section 105 transmits the output modulated signal w<SUB>1</SUB>, . . . w<SUB>L</SUB>, and the delay time t<SUB>1</SUB>, . . . , t<SUB>N </SUB>is shorter than a reciprocal number of a minimum value of clock rates of the multiple input received synchronized signals r<SUB>1</SUB>, . . . , r<SUB>N</SUB>, and is desirably proportional to one generated by a chaos random number in particular.
