Improvement of the open space network user authentication system Opengate

在本研究中，我们对我校已经开发的网络用户认证系统Opengate进行了改进。实现了IPv4/IPv6双栈流量控制。由于流量控制是基于IP地址进行的，所以IPv4地址和IPv6地址都需要知道。我们开发了一种双地址检测机制，实现了IPv4/IPv6双栈流量控制。为了提高便利性和稳定性，进行了许多修改，如下所示。更改了系统参数以集成到XML配置文件中。具体的用户组可以通过指定的参数进行控制。它与流行的安全认证协议兼容。我们开发了一种新的使用终止检测方法。以前，使用Java Applet来检测使用终止。但是Java VM在新浏览器中被省略了。因此，使用Java Script代替Java Applet，后者重复Ajax处理并维护与server.4的TCP连接。在Java Servlet环境下，实现了基本的系统。实现功能齐全、稳定的系统是未来的课题。开发的程序作为开源分发。为了方便开发人员，该项目已注册到源代码Forge.net。系统的用例正在扩展。

In this research, we improved a network user authentication system Opengate that has been developed in our University.1. We realized the IPv4/IPv6 dual stack flow control. Since flow control is performed based on the IP address, both the addresses of IPv4 and IPv6 are needed to know. We developed a mechanism for detecting the dual addresses, and implemented the IPv4/IPv6 dual stack flow control.2. Many revisions were performed for improvement in convenience and stability as follows. The system parameters were changed to integrate into the XML configuration file. Specific user group can be controlled by using specific parameters. It becomes compatible with popular and secure authentication protocols.3. We developed a new method for usage termination detection. Previously, Java Applet was used to detect the usage termination. But Java VM is omitted from new browsers. Thus Java Script was used instead of Java Applet, which repeats Ajax processing and maintains a TCP connection with server.4. Using the Java Servlet environment, basic system was realized. Implementation of full functional and stable system is a future issue.5. The developed program was distributed as an open source. The project was registered to Source Forge.net for the convenience of developer. The usage cases of the system are spreading.
