ABSTRACT:
Disclosed is an access control method using a token having security attributes in a computer system when a user gains access to a specific file. The computer system adopts a token having encryption, modification, execution, and provision attributes to determine access permission or access denial between a user and a file in such a way that a file access request is controlled. The access control method enciphers a file and stores the enciphered file in a storage unit, so that it can maintain security of the file even though the storage unit is stolen. The access control method enables a system manager to read only enciphered contents of the file when the system manager performs a data backup operation, thereby eliminating limitations in commonly operating a system simultaneously with maintaining file security. The access control method enables programs for executing operations on behalf of a user to automatically obtain a corresponding token, confirms authority to execute the file, and prevents that the authority is stolen or drained due to a program error.
