【摘要】 软件定义网络(SDN)技术分离了网络的控制平面和数据平面,有效地解决了网络安全管理和控制问题,然而SDN自身安全性也尚有诸多问题需要解决。本文在分析SDN架构及其安全性的基础上,针对南向通道安全进行了研究,并基于OTR协议给出了一种安全解决方法。该方法具有前向安全性、安全认证等特性,对于SDN环境中的安全身份认证、密钥安全保存以及SDN组件隐蔽保护等问题提供了较好的解决方案。更多还原

【Abstract】 The control plane and data plane are decoupled in SDN,which provides a new solution for network security management and control problems. However,there are still considerable issues presented by itself remaining to be solved. The architecture and security of SDN are analyzed in this paper.Based on OTR protocol,a secure solution of south channel is proposed. The method has the forward security and safety certification characteristics,which can give a solution to the SDN for the security of authentication,key security save and SDN component hidden protection.更多还原
