    摘要: A semiconductor device in related art has a problem that security at the time of writing data cannot be sufficiently assured. A semiconductor device of the present invention has: a unique code generating unit generating an initial unique code which is a value unique to a device and includes an error in a random bit; a first error correcting unit correcting an error in the initial unique code to generate an intermediate unique code; a second error correcting unit correcting an error in the intermediate unique code to generate a first determinate unique code; and a decrypting unit decrypting, with the first determinate unique code, transmission data obtained by encrypting confidential information with key information generated on the basis of the intermediate unique code by an external device to generate confidential information.

    摘要: 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).
