Embodiment Construction

[0028] Such as figure 1 As shown, the hard disk protection system of the present invention mainly includes a computer system 10, a hard disk 20 and a smart card 30; an encryption circuit 12 is arranged in the computer system 10, and data is encrypted with an encryption algorithm; There is a hard disk lock / unlock control circuit 14 for selectively locking or unlocking access to the hard disk according to the result of the password discrimination and the result of the authorization check. The computer system 10 can communicate with the smart card 30 through a smart card access device 40 , and can receive a password input by a user through an input device 50 . The hard disk 20 is installed in the computer system 10 . Generally speaking, the computer system 10 accesses the data recorded in the storage medium of the hard disk 20 via, for example, an IDE interface. The hard disk 20 is provided with: a hard disk password storage device 22, which is used to store a preset hard disk ...

Abstract

A method and its system for protecting hard disk of computer are disclosed. A first cipher is stored in a first smart card. When the head disk is restarted, the system requires the user to input a user cipher. A second cipher of second smart card is generated by interactive encryption / decryption between the system and the hard disk. The matching between the first and the second ciphers is checked. Then the smart card is authenticated. According to their results, the hard disk can be started or not.

Description

technical field [0001] The invention relates to a computer hard disk, especially a protection method and protection system for a computer hard disk. It is a protection system using a smart card to prevent data recorded in the hard disk of a portable computer from being illegally stolen. Background technique [0002] In recent years, the use of portable computers has become more and more popular, and their designs have gradually tended to be miniaturized. For the convenience of use and processing, most portable computer users will store data on the hard disk, including many important data such as research data or commercial secrets. However, also due to the small size and lightness of the portable computer, it is very easy to be stolen. Therefore, the portable computer must be provided with effective data protection measures to prevent the important data recorded in its hard disk from being stolen. [0003] Generally, a portable computer utilizes a power-on password protect...
