| abstract |
An information recording medium is provided with a security module, data to be recorded on the information recording medium are encrypted using encryption keys different for individual elements of data, and the security module keeps the encryption keys safely. Further, the security module performs a mutual authentication using a drive device and disclosed key encryption techniques, and gives an encryption key to a device after confirming that the device has received an authentic license to thereby prevent the leakage of data to an illegal device. Accordingly, an illegal copying (against the will of a copyright holder) of copyrighted data such as movie and music can be prevented. |
