    摘要: A masking addition operation apparatus for prevention of a side channel attack, includes a random value generation unit generating a first random value for a first input, second random value for a second input, and a summation random value. The masking addition operation apparatus includes an operation part performing an operation on the first and second random values, a previous carry input, and first and second masked random values generated based on the first and second random values. The masking addition operation apparatus includes a carry generator generating a carry input using a result of the operation part; and a summation bit generator generating a summation bit using the summation random value, the first and second random values, the previous carry input and the first and second masked random values.
