Remote attestation method based on cloud computing infrastructure as a service (IaaS) environment

Abstract

The invention discloses a remote attestation method based on a cloud computing infrastructure as a service (IaaS) environment. The remote attestation method is realized by an identity authentication module, a remote attestation module and a credible platform standard metric version updating module, wherein the identity authentication module comprises an attestation identity key (AIK) certificate application module, a Privacy CA certificate issuing module and an AIK request process verifying module; and the remote attestation module comprises a communication module for a challenger and an authenticated party, and a communication module for the challenger and a credible configuration server. The remote attestation method disclosed by the invention has the beneficial effects that a connection is permitted to be established only if virtual machines (VM) to be communicated are credible through a remote attestation by adding a remote attestation process before a normal communication channel is established between the virtual machines. On one hand, the remote attestation method disclosed by the invention can implement identity authentication and remote attestation on the authenticated party, and on the other hand, the authenticated party can update version under a situation that platform varies, so as to finally realize actually feasible remote attestation of the cloud computing IaaS environment.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a remote certification method based on cloud computing IaaS environment. Background technique [0002] With the development of information technology, more and more novel and practical technologies have appeared in the computer industry, and cloud computing technology is one of them. The industry, academia, government and other circles all pay close attention to the development of cloud computing, and cloud computing has become one of the hottest topics today. Relying on the Internet, cloud computing integrates a large number of storage resources, software resources and computing resources to form a large-scale warehouse of shared IT virtual resources, providing remote cloud computing users with information services that meet their needs. From another perspective, cloud computing has greatly reduced the operating cost and usage cost of IT services, accelerated the deployment spe...
