Reviewer 1 Report
1. Authors may revise the abstract to elaborate more on the problem statement, findings, and contributions and compare their results with the existing approaches.
2. How it contributes to the literature, in the second last paragraph of the introduction, the provided details are not sufficient
3. Authors may elaborate on the novelty of their work, and how this is significant over the existing approaches.
4. Overall, the paper presentation requires improvement.
5. A few of the figures are not clearly readable such as Figure 1
6. Thorough proofreading is recommended.
7. A few of the references are missing some information, may complete them critically
8. The conclusion is not clear and needs revision and clarity and alignment with the abstract and title
9. Provided references are better enough. However, authors are recommended to consider more latest and related such as,
Hussain, K., Jhanjhi, N. Z., Mati-ur-Rahman, H., Hussain, J., & Islam, M. H. (2021). Using a systematic framework to critically analyze proposed smart card based two factor authentication schemes. Journal of King Saud University-Computer and Information Sciences, 33(4), 417-425.

Reviewer 2 Report
The current version of the manuscript mainly focuses on the comparison of different references in form. The comparative analysis is not very reasonable and enough.
It is more like a daybook of reading instead of a paper to be published, and is short of proper summary and analysis.
It is recommended to classify the published works more carefully, and to analysis the performance of different certificateless authentication schemes under a similar constraint.

Reviewer 2:
Comment 1: The current version of the manuscript mainly focuses on the comparison of different references in form. The comparative analysis is not very reasonable and enough.
Response 1:
With respect to the reviewer comment 1, the manuscript also focuses on the advantages and limitations of the chosen references and it also highlights the parameters and goals met. The comparative analysis has been made reasonable by making changes necessarily in the manuscript which is subsequent.
Comment 2: It is more like a daybook of reading instead of a paper to be published, and is short of proper summary and analysis.
Response 2:
With respect to the reviewer comment 2, the manuscript has been modified by incorporating changing by including the summary and analysis for each authentication schemes accordingly.
Comment 3: It is recommended to classify the published works more carefully, and to analysis the performance of different certificate-less authentication schemes under a similar constraint.
Response 3:
With respect to the reviewer comment 3, the classification has been carefully reviewed and the analysis has been depicted by analyzing the performance aspects under a similar constraint.
