A Unified Point Multiplication Architecture of Weierstrass, Edward and Huff Elliptic Curves on FPGA

Round 1

Reviewer 1 Report

This paper designs and implements a unified point multiplication architecture on FPGA that supports Weierstrass, Edward and Huff Elliptic Curves. The architecture has the flexibility and advantage of supporting multiple curves. It also reduces the size of memory occupied. Experimental results on Xilinx V6 and V7 FPGAs have demonstrated the feasibility of the proposed architecture design. Overall, the paper is well-written.

 

Detailed comments:

1. The first paragraph of the intro can be a bit confusing. It is not clear why it starts from discussing the threat of quantum computers on ECC and RSA. It would be better to motivate the paper in a more straight-forward way.

2. It is recommended to report throughput in Table 4 as well.

3. It is not clear how the design enhances reliability. The paper also needs to stay consistent in reliability/security and security/reliability.

4. In line 397, the state numbers should be from 74 to 103.

Reviewer 2 Report

What are the main implications of the study? What changes in the real world with the study's findings? Inform in the abstract.

Avoid lumped references as they have small utility for other researchers

Avoid subsections in the Introduction (move section 1.1 for review). The Introduction should only contain the context of the article. More elaborate rationalizations and relation to the bibliography should go to section 2

Sections 1.2 and 1.3 should be merged with the Introduction. Briefly inform at the end of the Introduction which research method was used in the study

Consider unifying Sections 1.1 and 3 under a single heading, Hardware requirement, or similar

Sections 4 and 5 are fine

The last section needs to be better in front of the range of the study. Please delve much more profoundly, mainly discussing the real-world implications of the study results.
