A method for trusted measurement of a cloud computing platform includes: generating, by a third-party management and audit system, an audit report based on a current running indicator, signed by using a digital certificate, of a software and a running security indicator of the software, where the audit report indicates trustworthiness of a cloud computing platform. In this way, a process of trusted measurement of the cloud computing platform is open and transparent, so that authenticity of trusted measurement of the cloud computing platform is improved, thereby increasing a user's trust in the cloud computing platform.
