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.
Technology to solve this problem is disclosed in Japanese Patent Laid-Open Publication No. 2000-298942 entitled �Disk Storage Device and Copy Preventing System Applied to This Device�. In this document, data is encrypted when it is transmitted between the HDD and the host device. But, this technology has a disadvantage in that it takes considerable time to encrypt and decrypt a large amount of data.
SUMMARY OF THE INVENTION The present invention protects data without requiring extra hardware in a host of a data storage/retrieval system, through a series of processes including: encrypting command-related information, transmitting the encrypted information, and decrypting and restoring the encrypted information in a drive.
DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described more fully with reference to the attached drawings, in which exemplary embodiments thereof are shown.
