This invention relates to the intersection of cloud computing security, trusted computing, and hardware acceleration technologies, and discloses a virtual machine trusted state verification method and system based on TIPU. The method includes: configuring a measurement task on the host side of the TIPU, the measurement task containing the memory address information of the target virtual machine and its corresponding expected hash value; the TIPU directly reading the memory data of the target virtual machine via DMA based on the memory address information to generate an actual hash value; the TIPU comparing the actual hash value with the expected hash value to determine whether the target virtual machine is in a trusted state; when the virtual machine is determined to be in an untrusted state, the TIPU calls a built-in root of trust to sign the verification result and generate a remote proof report. This invention obtains the mapping table from the client's physical address to the host's physical address through the virtualization platform interface via a host agent and pre-configures it to the TIPU. The TIPU only accesses the target virtual machine's memory, achieving virtual machine context awareness and effectively avoiding cross-virtual machine information leakage.
