摘要： For protecting data during transmission between a host device and a data storage device, the host device encrypts command-related information and sends the encrypted command-related information to the data storage device. The data storage device decrypts the encrypted command-related information, interprets the decrypted command-related information to generate interpreted commands, and executes the interpreted commands.

摘要： For generating a random number in a disk drive, a seed is generated from a respective sector number for each of at least one sector of the disk drive. The random number is calculated using the seed. The seed that is generated with enhanced unpredictability and complexity is used to generate the random number for secure data cryptography within the disk drive.

摘要： A method and apparatus to authenticate a data processing apparatus having a recording device, according to which recording data to and restoring data from only an authenticated recording device can be performed. The authentication method to ensure legally recording of data to and/reproducing of data from a recording device in a data processing apparatus having a host to process data and the recording device to store and reproduce data processed or to be processed by the host, includes authenticating the recording device via the host; authenticating the host via the recording device; and performing recording of data to and/or reproducing of data from the recording device upon determining that the host and the recording device have authenticated each other. According to the authentication method, in a data processing apparatus having a recording device to record and/or store data, only when a host and the recording device authenticate each other, access to the recording device is permitted, that is, recording and/or restoring data is enabled such that illegal use of data or use of data by an unauthorized user can be prevented.

摘要： For protecting data within a data storage system, such as a hard disk drive, security enable mode is entered. In that mode, initialization data is moved from a first area of a disk to a second area of the disk with a location of the second area being randomly generated. The initialization data is then erased from the first area. Also, a first cipher for firmware and a second cipher for a disk are both changed into a randomly generated value. Later, access to the initialization data from the second area is granted in the security enable mode if the first and second ciphers are the same.
