摘要： A packet intrusion detection rule simplification apparatus and method and an intrusion detection apparatus and method are provided. Test conditions of at least one intrusion detection rules are rearranged based on test items, and the same test conditions for the same test items are grouped. Group rules having a connection structure of the test conditions are generated so that the test items and orders of the intrusion detection rules are satisfied. A common rule consisting of test conditions existing at the test start positions in the connection structure of the group rules is generated. Next, packet intrusion detection is performed by using the common rule, and the packet intrusion detection is performed by using the group rules. According, it is possible to reduce a load involved in the intrusion detection process by using the grouped and simplified intrusion detection rules.

摘要： Provided is a method for providing an anonymous public key infrastructure (PKI) in a user terminal. The method includes receiving a real-name certificate from a real-name PKI service domain, requesting an anonymous certificate to an anonymous PKI service domain, and receiving the anonymous certificate from the anonymous PKI service domain. Accordingly, the method can ensure anonymity when a user uses a service by providing the anonymous certificate in association with the PKI-based real-name certificate.

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。

摘要： Disclosed herein is a method of providing a trusted path between a client and a system using an access control processing technique. The method of providing a trusted path between a client and a system includes the step of determining whether access to resources of the system will be permitted or refused on the basis of access control rules and databased attributes set by a security administrator. Thereafter, the client is notified of permission for or refusal of the access in accordance with the result of the determination.
