Virtual desktop technology separates the users and the resources, contributing to terminal security solutions and improvement of resource utilization.It also provides the convenience for the centralized management of resources.But the introduction of virtualization technology also makes unique safety risks existing in virtual desktop.Identity authentication is the key technology to solve the problem of virtual desktop security problems and also is the foundation of more complex security protective measures.This article first describes the principle of the Combined Public Key (CPK) cryptosystems, then according to the characteristics of the virtual desktop, two authentication methods based on CPK are proposed for virtual resources applying and virtual resources using respectively.And the user and the virtual machine is bound through the federated identity in order to prevent fraudulent use of virtual machine,.At last, the safety and performance analysis of the proposed authentication method is given.
