METHOD FOR PROVIDING SAFETY OF VIRTUAL MACHINE INSTALLATION IN CLOUD COMPUTING ENVIRONMENT

摘要

PURPOSE: A virtual machine installation supplying method in a cloud computing environment in order to safely install a virtual machine image is provided to protect data privacy intrusion of a user by safely installing the virtual machine of a user. CONSTITUTION: A verification center verifies the integrity of a virtual machine node by using a TPM(Trusted Platform Module). The virtual machine of a user terminal is installed in the virtual machine node. A cryptographic key of the user terminal is set up through the verification center. An encrypted virtual machine image is received from the user terminal by using the cryptographic key. The encrypted virtual machine image is installed(S237).
