A first semiconductor device includes a processor configured to generate a random number at initial test of a second semiconductor device after fabrication of the second semiconductor device in a supply chain related to the second semiconductor device, and send the generated random number to the second semiconductor device. The processor is further configured to receive a first signature that is signed over the sent random number by the second semiconductor device using a first private key that is stored in the second semiconductor device, among a first private and public key pair, and test the received first signature, using a first public key that is stored in the first semiconductor device, among the first private and public key pair, to determine whether the second semiconductor device is authenticated.
