Arithmetic Devices, Montgomery Parameter Calculation Method and Modular Multiplication Method Thereof |
| 摘要 |
Disclosed are arithmetic devices, a method of a Montgomery parameter calculation thereof and a Montgomery multiplication method thereof. The method of the Montgomery parameter calculation of the arithmetic devices includes detecting a position of a most significant bit (MSB) of a modulus, calculating an initial value using position information about the detected MSB, and calculating an intermediate value and a Montgomery parameter by repeatedly performing a Montgomery addition or a Montgomery multiplication with respect to the initial value. |

1. A method for calculating a Montgomery parameter in an arithmetic device, the method comprising:
detecting a position of a most significant bit (MSB) of a modulus; calculating an initial value using position information about the detected MSB; and calculating an intermediate value and a Montgomery parameter by repeatedly performing a Montgomery addition and/or a Montgomery multiplication with respect to the initial value. |
