A provider of the mobile communication program obtains the public key generated on the basis of a unique terminal identification number (IMEI) unique to an SDR terminal by a key generation algorithm, registers the generated public key in a key registration server, encrypts a mobile communication program with the public key, and distributes the encrypted program. The SDR terminal generates the private key on the basis of the unique terminal identification number (IMEI) by the key generation algorithm, decrypts the encrypted program downloaded from a server with the generated private key, and installs and operates the decrypted program. Since the mobile communication program is encrypted, although a third person tries to install an illegal copy program in an SDR terminal, the decryption is impossible, and the installation becomes impossible. In addition, it is possible to prevent ill-intentioned corruption and illegal reuse of an illegal copy program by the third person.
