A Novel Secure End-to-End IoT Communication Scheme Using Lightweight Cryptography Based on Block Cipher

Round 1

Reviewer 1 Report

The paper proposes an interesting method for secure end-to-end IoT communications. The paper is well organized and written. I have a comment.

-       All comparisons are done in sense of time and complexity. I suggest that the authors also compare different schemes in sense of security.
