Implementing method for dynamically transparent virtual credible platform module

Abstract

The invention provides a method for seamlessly running trusted application software based on TPM 1.2 standard in virtual domain in Xen virtual machine environment, the components of the method comprise a virtual TPM (vTPM) device carried out in privilege domain, a vTPM device management tool, a vTPM back-end driver, a virtual domain management tool for supporting vTPM and a vTPM front-end driver implemented in virtual domain. An independent vTPM device which is provided with all the functions of the physical TPM is provided for each running virtual domain in privilege domain in the invention; the vTPM device can be created and deleted dynamically. By efficiently and organically coordinating with all the components, the reusability and demultiplexing of trusted data steam are realized, the communication between the vTPM device and the corresponding virtual domain is ensured, and trusted computing based on independent TPM in the virtual domain is realized.

AI Technical Summary

Benefits of technology

This patented technology allows for securely managing large amounts of sensitive digital assets (such as credit card numbers or bank details). It uses an improved version of Virtual Machine Device Initialisation Protocol (VTM), which simplifies the initializing procedure while still ensuring security during operation. Additionally, it supports multi-task execution environments where different types of applications work together on behalf of one another without interferring their own operations. Overall, this technology provides better performance capabilities than previous methods like VTAM systems due to its ability to efficiently manage complex cryptographic keys across various parts of the world.

Problems solved by technology

This patented describes how different types of applications can work together without compromising any one's own capabilities. It proposes introduces new technologies like Virtual Machine Technology (VM), Trustworthiness Group Technology (TG). These techniques aim to provide better access control mechanisms, reduce complexity, redundancy, and power consumption while improving overall functionality and usherment into a seamless world where all machines run at once.
