An electronic device and a program management method therefor are provided. The electronic device includes a communication interface, a memory, at least one processor, and a secure circuitry. The secure circuitry is configured to provide a first public key stored in the secure circuitry to the at least one processor. The at least one processor is configured to transmit the first public key to an external device and receive an encrypted secure program encrypted based on the first public key and a second public key generated by the external device, from the external device. The at least one processor is further configured to transmit the second public key and the encrypted secure program to the secure circuitry. The secure circuitry is configured to decrypt the encrypted secure program based on the second public key and a first private key which is symmetrical to the first public key.
