摘要
采用云计算技术实现托管式的虚拟桌面一般被称为桌面云。近年来桌面云被认为是云计算最为成熟的应用之一,本文着重研究桌面云安全访问与共享机制。我们使用基于PKI的证书认证建立了虚拟组织,在其上重点研究了虚拟机的创建,远程桌面访问,共享等应用。证书认证等机制可以使得访问更加安全可靠。而通过虚拟组织的信任关系,多个用户可以共享同一个虚拟机。为了确保远程通道的安全,我们采用了OpenVPN来构建虚拟专用网络,对虚拟机的使用者进行认证并对通信进行加密保护。
A desktop cloud is an implementation of hosted virtual desktops using cloud computing technology. Desktop clouds are one of the most popular applications for cloud computing. In this work, mechanisms for secure accessing and sharing of virtual desktops are investigated in details. The public key infrastructure (PKI) is utilized to create virtual organizations (VO). Within a VO, virtual machines are created, remote desktops are accessed and shared. PKI provides security mechanism and multiple users can share a virtual machine via VO trust management. In order to make remote channels secure, OpenVPN is adopted to build a private network, authenticating users and encrypting communications.
