Abstract
A modular operation circuit includes a controller, a modular multiplier and a modular adder. The controller divides a first number into K segments. The modular multiplier performs modular multiplication operations and the modular adder performs modular addition operations to the K segments in (K−1) iterations for deriving a remainder of a division of the first number by a second number.
