Migration virtual trusted platform module state using TPM emulator

The purpose of this study is to investigate the application of Virtualization Trusted Platform Module (vTPM) and migration of vTPM states and develop a simulation migration model between platforms. TPM Emulator, software based TPM was used as the benchmark for the proposed vTPM. A vTPM instances between platforms based on modified TPM Emulator has been proposed in this study to reduce problem of migration vTPM states between platforms. The effect of different combination of UNIX domain socket and TCP socket on the platforms of the developed simulation migration model was studied and the effectiveness and shortcoming of TPM Emulator were highlighted. Results were compared between previous TPM Emulator running instances on single host platform and between platforms. It was discovered that modified TPM Emulator can perform the vTPM instances not only in single host platforms however includes between platforms. In addition, the use of simulation migration model was also proposed and investigated, named as Virtual Machine Monitor Management (vTPM Manager) to handles vTPM state life cycles. Simulation migration vTPM states results demonstrated that vTPM instances are able to be created and saved between platforms. Furthermore, from the case studies of vTPM challenges showed that the proposed simulation migration could be used as an alternative platform to adequately identify adequate and complete models for vTPM states life cycles
