Abstract
Provided are a modular multiplication method with an improved arithmetic operation, a modular multiplier and a cryptograph calculating system having the modular multiplier. The modular multiplication method comprises performing a first arithmetic operation including a first multiplication on a first bit string of a multiplicand and a first bit string of a multiplier and a first reduction for eliminating partial bits of the first multiplication result, performing a second arithmetic operation including a second multiplication on a second bit string of the multiplicand and a second bit string of the multiplier and a second reduction for eliminating partial bits of the second multiplication result, and calculating a modular multiplication result using the result of the first arithmetic operation and the result of the second arithmetic result. The first arithmetic operation and the second arithmetic operation are independently performed.
