MANET中安全聊天室的设计与优化

The Design and Optimization of Secured Chat Room in MANET

移动自组织网络是一种动态的网络,该网络中的结点的动态加入和退出使得网络聊天室面临很多的安全问题。针对于这些问题,通过优化和设计了访问券授权中心来加强其安全性和简化其复杂性;通过建立证书授权中心和访问券授权以及访问控制的三位一体的实现方案,完成了优化的身份验证和聊天室的访问控制;通过测试可知新的优化方案简化了安全聊天室在成员加入时的复杂性,强化了成员加入时的安全性。

Mobile ad hoc networks is a dynamic network,the dynamically joining and exiting of network node makes the network chat rooms facing a lot of security issues.The security is strengthened and the complexity is simplified by optimizing and designing a ticket-granting center in this paper.Through the establishment of Certificate Authority Center and ticket-granting,as well as implementation of access control scheme the optimization of the authentication and chat room access control is completed.The test shows that the new optimization solutions simplify the complexity and reinforce security of secured chat room in the members joining.
