The invention provides a safe and credible operation protective method based on a virtual platform. According to the safe and credible operation protective method based on the virtual platform, focusing on the safety problem existing on the virtual platform, a safe and credible operation protective model of the virtual platform is obtained through combination of a virtual machine hypervisor static analysis module based on an LLVM, a platform integrity remote verification module based on a TPM and an IPMI, a management domain virtual machine integrity measurement module, a user virtual machine integrity measurement module and a data flow consistency analysis module based on software behaviors based on the wide application of the cloud computing virtual technology, the situation that safety challenges related to the virtual technology are brought by the virtual technology, and the condition that the trusted computing technology for guaranteeing the safety of a system and hardware in information safety is gradually mature. According to the safe and credible operation protective method based on the virtual platform, the trusted computing technology is introduced into the virtual platform, through the protective modes such as dynamic measurement, a management domain, a virtual machine hypervisor and client domain operation integrity, a safe and credible platform is established; trusted transmission by a trust chain is used as a model of trusted computing, the absolute credibility of continuing of an upper chain and a lower chain of the virtual platform can be protected, and therefore the safe and credible operation of the virtual platform is guaranteed.
