Abstract: A method for processing homomorphic ciphertexts includes: receiving an input of an instruction for sorting regarding a plurality of homomorphic ciphertexts; sorting the plurality of homomorphic ciphertexts by using a sorter which can sort 3 more homomorphic ciphertexts in a single stage; and outputting the sorting result. The sorter performs sorting by using a comparison function that selectively outputs a bigger value or a smaller value between two input values.
