Abstract
A cloud computing environment includes a key management server and a cloud computer system running several virtual machines. A virtual machine hosted by the cloud computer system includes an integrity check module for checking the integrity of the virtual machine and getting identity information of the virtual machine. The integrity check module sends a key request to a key management server, which provides key service to different cloud computer systems. The key management server validates the request and, if the request is valid, provides the key to the virtual machine. The key is used to unlock an encrypted file system in the virtual machine.
