Abstract: Provided are a security processor for performing a remainder operation by using a random number and an operating method of the security processor. The security processor includes a random number generator configured to generate a first random number; a modular calculator configured to generate a first random operand based on first data and the first random number and generate output data through a remainder operation on the first random operand, wherein a result value of the remainder operation on the first input data is identical to a result value of the remainder operation on the first random operand.
