Abstract
Provided are an electronic apparatus and a method for verifying encrypted data. The verification method of the electronic apparatus includes transmitting encrypted quotient polynomial rings to an external device, receiving, from the external device, a result value calculated through an operation process for at least one layer on the basis of the transmitted encrypted polynomial rings, transmitting a random value to the external device, and receiving claim data obtained by performing the operation process in a reverse order on the basis of the random value from the external device, and verifying the received result value on the basis of a value of the quotient polynomial rings corresponding to the random value and the received claim data.
