Abstract:
1. A semiconductor device comprising: a unique code generating unit which generates an initial unique code, the initial unique code being a value unique to the semiconductor device and including an error in a random bit; a first error correcting unit which corrects the error in the initial unique code to generate an intermediate unique code; a second error correcting unit which corrects an error in the intermediate unique code to generate a first determinate unique code; and a decrypting unit which decrypts, with the first determinate unique code as first encryption key information, transmission data received from an external device, the transmission data being generated by the external device by encrypting confidential information with second encryption key information generated by the external device on the basis of the intermediate unique code, the decrypting reproducing the confidential information, wherein the confidential information includes: wherein the semiconductor device further comprises:
