Reviewer 2 Report

This paper needs a major revision,

- Please indicate the insights obtained by your work

- Please simulate with large M, e.g., 32,64

- Please survey more papers on physical layer security of RIS. The following paper should by cited: Artificial Noise Aided Secure NOMA Communications in STAR-RIS Networks

Reviewer 3 Report

First, in terms of content, it is estimated at the level of a conference paper, and both in terms of the number of references and attention to other layers - beyond just the physical layer - the text should be strengthened. Secondly, a similar article by the first three of the four present authors can be seen at the following address:

https://journal-home.s3.ap-northeast-2.amazonaws.com/site/2022s/abs/0750.pdf

So it is necessary for the authors to explain that the current work is really so different from this article that they considered it suitable for submission in the journal?!

Thank you for your comments.

Reviewer 3 Report

In part 2, which you mentioned about learning algorithms, the following paper should be cited:

Author Response

We have tried to understand Reviewer 3's comment but we think the suggested link by Reviewer 3 is incorrect.  The research area of the suggested paper is quite different from ours.

Title of the suggested paper: "Less primary fistula failure in hypertensive patients"
Research Area: Journal of Human Hypertension

Title of our paper: "Physical-Layer Security with Irregular Reconfigurable Intelligent Surfaces for 6G Networks"
Research Area: Wireless Communication
