A modular operator, a smart card including the same, and a method of operating the same are provided. The modular operator includes: an input unit configured to receive first data, second data, and a modulus; and an accumulator configured to perform an accumulation operation on the first data and a first portion of the second data, to shift the accumulation operation result to the right as much as the number of bits of the first portion, and to perform an accumulation operation on a result of a shifted accumulation operation, a second part, of the second data, which is shifted to the right as much as the number of bits of the first portion, and the modulus. |
