Abstract

A method of automatically encrypting and decrypting a file in kernel, a method of moving a file pointer using the same, and a computer readable recording medium on which programs produced by programming the above methods are recorded are disclosed. In the method of automatically encrypting and decrypting a file in kernel, when a user process of a UNIX operating system intends to write a file to a storage device such as a disk, diskette, or CD-ROM, the file is automatically encrypted block by block, and stored in the storage device in kernel mode of the operating system without respect to user's intention, and when the user process intends to read the encrypted file, the whole data of the file or a necessary portion of the data is automatically decrypted block by block in kernel mode. In addition, when a file pointer is moved in an encrypted file according to the method of moving a file pointer, the amount of file movements is calculated while the file is automatically decrypted block by block according to the method, and then the file pointer is moved based on the calculated value. The recording medium is a predetermined recording medium on which programs produced by programming the method of automatically encrypting and decrypting a file in kernel, and the method of moving a file pointer using the same are recorded.
