摘要： 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.
摘要翻译：公开了当用户获得对特定文件的访问时，使用在计算机系统中具有安全属性的令牌的访问控制方法。计算机系统采用具有加密，修改，执行和配置属性的令牌来确定用户和文件之间的访问许可或访问拒绝，使得文件访问请求被控制。访问控制方法加密文件并将加密文件存储在存储单元中，使得即使存储单元被盗，它也可以保持文件的安全性。当系统管理者进行数据备份操作时，访问控制方法使得系统管理者仅读取文件的加密内容，从而消除了在保持文件安全的同时同时操作系统的限制。访问控制方法允许代表用户执行操作的程序自动获得相应的令牌，确认执行该文件的权限，并且防止由于程序错误而导致该机构被盗或者被排除。
