【摘要】 软件定义网络的发展使得其对信息安全的要求越来越高,匿名通信成为软件定义网络的关键研究点。由于软件定义网络特有的管控分离性能,传统网络中的匿名方案难以在其平台应用。提出一种新的软件定义网络匿名通信方案,通过重写数据包实现其匿名性,通过扩展Open Flow协议实现数据包的正常转发,并且采用新的最大值随机路径算法保证通信路径的隐匿性,实现基于软件定义网络的低延迟、高匿名传输。更多还原

【Abstract】 With the development of software defined network, the requirement of information security is becoming higher and higher. Anonymous communication has become the key research point of software defined network. Due to the special separation of control in software defined network, it is difficult to apply anonymous scheme in traditional network to this platform. This paper introduces a new software defined network anonymous communication scheme. The anonymity of packets was realized by rewriting them, and the normal forwarding of packets was realized by extending Open Flow protocol. A new maximum random path algorithm was adopted to ensure the hidden of communication path, and low delay and high anonymous transmission based on software defined network was realized.更多还原
