Abstract

The invention discloses a method and system for proving the integrity of a cloud computing platform. The method is used for proving the integrity of the platform based on a composite trust chain, wherein the composite trust chain comprises a static trust chain provided by a cloud end virtual machine and a dynamic trust chain system constructed by a remote verification party. The method comprises the steps of static trust chain construction and dynamic trust chain system construction and verification, wherein in the static trust chain construction step, the static trust chain is constructed through a virtualized trusted platform module provided by the cloud end virtual machine; in the dynamic trust chain system construction and verification step, the dynamic trust chain system is constructed by the remote verification party, platform integrity verification is conducted in a trusted executing environment, and the operation evidence of the trusted executing environment is generated by the remote verification party, so that the virtual machine can trust a received verification result more safely.

Description

technical field [0001] The technical field to which the invention belongs is the field of system security and trusted computing. The present invention relates to cloud computing platform integrity certification, which involves trusted computing organization (Trusted Computing Group, referred to as TCG) trusted platform module and Intel's trusted execution technology, belongs to the field of trusted computing and cloud computing security, in particular to a A cloud computing platform integrity certification method and system thereof. Background technique [0002] Cloud computing is an Internet-based computing method in which shared hardware and software resources and information can be provided to computers and other devices on demand. As a new type of computing model, while cloud computing provides users with convenient services, it also poses new challenges to its security and credibility due to its third-party computing characteristics. The virtualization technology prov...
