Abstract: PURPOSE: The method for improving the operation system of the cryptographic system is provided to run the constant multiple operation as an elliptic curves operation of a smaller number than a half of the binary bit number of the relevant constant, and to offer the recorded media which can read the program of implementing the method by a computer. CONSTITUTION: An arithmetic unit of the cryptographic system receives the order of the finite field and the integer(100), runs the constant multiple operation according to the window size on a random point(102), and gets the a mapping and the coefficient of the mapping(104). The arithmetic unit runs the constant multiple operation of the point on the elliptic curves using the mapping(106) and outputs the result of the constant multiple operation of the point on the elliptic curves(108).
