Abstract
An electronic apparatus for generating a homomorphic encrypted message includes: a processor configured to generate a mask homomorphic encrypted message by homomorphically comparing the homomorphic encrypted message with the index data in case that a calculation command of the predetermined function for the homomorphic encrypted message is input, generate an intermediate homomorphic encrypted message by homomorphically multiplying the generated mask homomorphic encrypted message by the function result data, generate a function-result encrypted message for the homomorphic encrypted message by computing sum of values in a plurality of slots of the intermediate homomorphic encrypted message.
