TL;DR

This paper responds to a comment on a quantum communication protocol, clarifying misconceptions, correcting attack rate calculations, and providing a comprehensive analysis of eavesdropping strategies to strengthen the protocol's security understanding.

Contribution

It addresses and corrects errors in previous critique, offering a detailed analysis of eavesdropping attacks on a deterministic six-state quantum protocol.

Findings

Corrected intercept-and-resend attack rates

Completed analysis of double CNOT gate attack

Clarified misconceptions about the protocol's security

Abstract

We reply to the Comment made in arXiv:1107.4435v1 [quant-ph] (Phys. Lett. A \textbf{374} (2010) 1097) by noting some erroneous considerations therein resulting in a misleading view of the quantum key distribution protocol in question. We then correct the rates provided for the Intercept-and-Resend attack and we complete the analysis of Eve's attack based on a double CNOT gate.
