A method and electronic device are provided for decrypting homomorphically encrypted (HE) data. The method may include generating, in the electronic device, result metadata that specifies a size of the HE data to be decrypted. The electronic device generates or collects HE input data and the result metadata. The HE input data and the encrypted result metadata are transmitted to a cloud server in a cloud environment to allow the cloud server to perform computations using the HE input data. The cloud server is enabled by the hardware device to send a result of the computations on the HE input data to a secure element (SE) for decryption. A relatively secure online connection is established to the SE in the cloud environment. The SE is enabled by the electronic device to decrypt the result of the computations on the HE input data as specified by the result metadata.
