description Provided is a cryptographic communication system including a first semiconductor device and a second semiconductor device. The first semiconductor device includes a common key generation unit that generates a common key CK(a) by using a unique code UC(a) and correction data CD(a), and an encryption unit that encrypts the common key CK(a) generated in the common key generation unit by using a public key PK(b) of the second semiconductor device. The second semiconductor device includes a secret key generation unit that generates a secret key SK(b) by using a unique code UC(b) and correction data CD(b), and a decryption unit that decrypts the common key CK(a) encrypted in the encryption unit by using the secret key SK(b).
