| In this scheme, the devices that deploy TPM are used to provide trusted services to the devices without TPM protection through the network, so as to guarantee the trusted boot of embedded smart devices.
I don't understand "TPM are used to provide trusted services to the devices without TPM protection through the network", what do you mean? |
In my paper, the corresponding measurement method is designed so that the trusted status value of the embedded devices without TPM is stored in the NV of TPM in advance, and then the trusted communication protocol is used to guarantee the secure boot of the embedded devices without TPM. |

| Will you tell us what is the major achievement of this paper, and also what is further study issue from this? Thanks in advance!! |
My achievement is as follows: For embedded smart devices without TPM,A novel trusted boot model to provide trusted service for NTESD is presented in this paper, which uses TPM in TESD to make NTESD boot credibly. The security protocols presented in this paper are proved by BAN logic, which can prove that they are credible. And now I have built a prototype system to test my scheme. |

| First of all, thank you for the good research paper and presentation contents. I would like to know more about the research environment used in this study, and also in detail about the equipment & operating systems, development languages and software libraries you used. |
I deployed the experimental environment on raspberry PIs, developed the relevant communication protocol using c++, and used TPM API library. |

| Firstly, the research on A Novel Trusted Boot Model is very meaningful.
What is your experimental data set? What problems does your research solve in the real environment? |
The experimental data in this paper are calculated by hashing the embedded smart devices without TPM chip in a secure environment, and then stored in TPM chip to provide trusted services. My research solved the problem of trusted boot for small embedded devices that could not install TPM chips in real world. |

| Dear Author, you have a very good research. I would like to know if the technology today is capable of implementing your proposed scheme? Is there an existing technology almost similar to your proposal that has been deployed in real world environment? Thank you and stay safe. |
The existing technology can implement my solution, but no relevant technology is currently deployed in the real world. |

| Dear author, you have done a good research. What are the advantages of your model over other models? What are the current shortcomings? What will the future research focus on? Thank you. |
The advantage of this model is that it can avoid deploying a TPM chip on each embedded device, which not only avoids unnecessary economic costs, but also ensures that the volume of the embedded device meets the requirements. The disadvantage of this model is that additional secure communication protocols need to be added, which increases the network overhead between devices. I will make improvements through experiments and optimize the defects of the existing design model. |

| How's the experiment going? Is there any comparison with other methods? What was the result? |
At present, a prototype system has been established and the functions and performance of the proposed scheme are being tested. Comparative tests will be carried out in the future. |
