Abstract
An operation apparatus performing matrix multiplication of a homomorphic encryption is disclosed. The operation apparatus includes a memory configured to store at least one instruction and a plurality of homomorphic ciphertexts, and a processor configured to execute the at least one instruction. The processor is configured to generate first matrix data having a row of a predetermined size and a column of a predetermined size using the plurality of homomorphic ciphertexts, generate a plurality of third matrix data having a row which is the size of the predetermined column and the column of the predetermined size by arranging second matrix data having a row which is 1/n size of the predetermined column and the column of the predetermined size sequentially n-times, and perform a homomorphic multiplication operation between same rows and same columns using the first matrix data and the generated respective third matrix data.
