Abstract
Disclosed is an electronic device. The electronic device includes a communicator, a memory configured to store data for generating a key, and a processor. The processor may generate a secret key by randomly combining values within a preset range based on the data stored in the memory, generate a public key using the secret key and an error, and store the secret key and the public key in the memory, transmit the public key to an external device using the communicator, and a sum of the number of remaining values other than zero (0), among the values within the preset range, may correspond to a Hamming weight. Accordingly, encryption and decryption may be performed efficiently.
