<P>PROBLEM TO BE SOLVED: To enhance security of an encryption communication system. <P>SOLUTION: An encryption communication system comprises a semiconductor device 10 and a semiconductor device 20. The semiconductor device 10 comprises: a common key generation unit 13 for generating a common key CK (a) by using a unique code UC (a) and correction data CD (a); and an encryption unit 14 for encrypting the common key CK (a) generated by the common key generation unit 13 by using a public key PK (b) of the semiconductor device 20. The semiconductor device 20 comprises: a secret key generation unit 23 for generating a secret key SK (b) by using a unique code UC (b) and correction data CD (b); and a decryption unit 24 for decrypting the common key CK (a)' encrypted by the encryption unit 14 by using the secret key SK (b). <P>COPYRIGHT: (C)2013,JPO&INPIT |
