ABSTRACT:
The present invention relates to a modular multiplication device for information security which needs only the hardware almost half as much as required in a conventional modular multiplication device wherein multiplication and division circuits are separately used, by performing a dual function of multiplication and division with a binary adder. The modular multiplication device for information security in accordance with the present invention comprises binary addition means for performing a binary addition operation; two bit processing means for processing the output of the binary addition means; least significant two bit register means for sequentially storing least significant two bits; signed digit decoding means for generating a signed digit for a multiplier; result register means for storing a result value of the binary addition means; comparison means for comparing a result value of the result register with a modular value; decimal processing means for processing an output value for the modular value; multiplexing means for selecting output values of the decimal processing means and the signed digit decoding means; inverter means for inverting the multiplication/division selection signal; first AND gate means; second AND gate means; and third AND gate means.
