Claim 1:
2. The secure computing device according to claim 1, wherein the computer program instructions further perform processing of:
generating a random bit string using a bit string in which a value of each digit is one of two values determined on the basis of a prescribed probability distribution as the random bit string,
wherein the computer program instructions perform processing of:
determining a value of each digit of a bit string representing the sum as one of a value of a corresponding digit of the bit string that represents the first encrypted data and is represented in the expression format and a value of a corresponding digit of the bit string that represents the second encrypted data and is represented in the expression format on the basis of a value of a corresponding digit of the random bit string in the process of acquiring the sum that is a sum of the first encrypted data and the second encrypted data using the random bit string when the sum is acquired.
