摘要
PURPOSE: A system and a method for the real time security of a hard disk are provided to automatically encrypt or decrypt the file stored in a directory selected by a user according to a password key value of the user without encrypting and decrypting respective files by encrypting the data in the hard disk by a directory unit. CONSTITUTION: The system comprises a smart card(170) storing and managing the password key value using to encrypt the data, a hard disk manager(110) assigning the data as an encryption area by using the password key value and a hard disk event detector(120) detecting a write and read event for the data in the encryption area and requesting the encryption area assignment of the data. An encryption board(150) encrypts the data transmitted from the hard disk event detector by receiving a request for the encryption area assignment from the hard disk event detector through a PCI(Peripheral Component Interconnect) set register. The PCI operator(130) for the hard disk encryption board makes the hard disk real time security system recognize the encryption board by using the PCI set register.
