Abstract:
For calculating the result of a sum of a first operand and a second operand, a modified second operand is calculated, which is negative and less than the modulus. Based on this modified second operand, a sum is calculated which is less than a maximally processable number of a calculating unit executing the calculation. Finally, the sum calculated using the modified second operand is reduced, namely with respect to the modulus, to obtain the result of the sum of the first and second operands.
