Abstract
An encryption computing system may include; a processor performing calculations between homomorphic encrypted data including cyphertexts, and a non-volatile memory device storing the homomorphic encrypted data. The processor performs a first multiplication between a first cyphertext and a second cyphertext to generate a first intermediate cyphertext, performs a second multiplication between the first intermediate cyphertext and a third cyphertext to generate a second intermediate cyphertext, performs a third multiplication between the second intermediate cyphertext and a fourth cyphertext to generate a third intermediate cyphertext, and thereafter, performs a rescaling calculation on the third intermediate cyphertext using a cumulative scaling factor to generate the homomorphic encrypted data, wherein the cumulative scaling factor is defined in relation to the first multiplication, the second multiplication and the third multiplication.
