摘要： Provided is a method of copying data stored in a first storage medium to a second storage medium. The method includes recording the encrypted data stored in the first storage medium on the second storage medium; reproducing a first content key, which is used to encrypt the encrypted data, using a first drive into which the first storage medium is loaded; encrypting the first content key; sending the encrypted first content key to a second drive into which the second storage medium is loaded; and recording the encrypted first content key on the second storage medium. In this method, encrypted data stored in a first storage medium is sent to a second storage medium via a host without decrypting the encrypted data, thereby preventing the data from being hacked or being accessed by unauthorized users and increasing a speed of copying the encrypted data.

摘要： A method of and an apparatus for copying and decrypting encrypted digital data. The method of copying encrypted digital data includes encrypting a first media key block to be used for decryption of the encrypted digital data using a predetermined key of a second information storage medium and storing the encrypted digital data and the encrypted first media key block in the second information storage medium. Security of data encryption is heightened by not discarding an encryption key used for an initial encryption, encrypting the encryption key used for initial encryption using another encryption key used for a second encryption, and storing the encrypted encryption key with the data. Also, since unnecessary decryption and encryption of data are not repeated, the time required for copying data is reduced, and since data is transferred between apparatuses in an encrypted state, a security level is higher.

摘要： A method and apparatus for restricting the use of a disc are provided. In this method, first, lead-in data is read out from a loaded disc. Then, a user key is read out from a lead-in area of the disc. Thereafter, the user key undergoes authentication based on a user key received from a host. The authentication is performed by comparing a random number produced by a disc drive with a decrypted random number obtained by the disc drive decrypting a random number encrypted by the host. Accordingly, the use of the disc by an unauthorized third person is restricted, thus preventing a leakage of personal information and a protection of the copyrights of data.
