Classical Authentication Aided Three-Stage Quantum Protocol

Published May 18, 2006• 6 citations
arXivHTMLPDF

Abstract

This paper modifies Kak's three-stage protocol so that it can guarantee secure transmission of information. Although avoiding man-in-the-middle attack is our primary objective in the introduction of classical authentication inside the three-stage protocol, we also benefit from the inherent advantages of the chosen classical authentication protocol. We have tried to implement ideas like key distribution center, session key, time-stamp, and nonce, within the quantum cryptography protocol.

Comparing BB84 and Authentication-Aided Kak's Three-Stage Quantum Protocol

Partha Basuchowdhuri

This paper compares the popular quantum key distribution (QKD) protocol BB84 with the more recent Kak's three-stage protocol and the latter is shown to be more secure. A theoretical representation of an authentication-aided version of Kak's three-stage protocol is provided that makes it possible to deal with the man-in-the-middle attack.

Variations on Kak's Three Stage Quantum Cryptography Protocol

James Harold Thomas

This paper introduces a variation on Kak's three-stage quanutm key distribution protocol which allows for defence against the man in the middle attack. In addition, we introduce a new protocol, which also offers similar resiliance against such an attack.

Trusted Certificates in Quantum Cryptography

William A. Perkins

This paper analyzes the performance of Kak's three stage quantum cryptographic protocol based on public key cryptography against a man-in-the-middle attack. A method for protecting against such an attack is presented using certificates distributed by a trusted third party.

A Three Party Authentication for Key Distributed Protocol Using Classical and Quantum Cryptography

Suganya Ranganathan, R. Nagarajan, S. Karthick +4 more

In the existing study of third party authentication, for message transformation has less security against attacks such as man-in-the-middle, efficiency and so on. In this approach, we at hand give a Quantum Key Distribution Protocol (QKDP) to safeguard the security in larger networks, which uses the combination of merits of classical cryptography and quantum cryptography. Two three-party QKDPs, one implemented with implicit user authentication and the other with explicit mutual authentication, which include the following: 1. Security against such attacks as the man-in-themiddle, eavesdropping and replay. 2. Efficiency is improved as the proposed protocols contain the fewest number of communication rounds among the existing QKDPs. 3. Two parties can share and use a long-term secret (repeatedly). To prove the security of the proposed schemes, this work also presents a new primitive called the Unbiased-Chosen Basis (UCB) assumption.

Quantum no-key protocol for direct and secure transmission of quantum and classical messages

Li Yang

We present a quantum no-key protocol for direct and secure transmission of quantum and classical messages based on simple Boolean function computation with several quantum gates and Shamir's interactive idea of classical message encryption. This protocol has inherent personal identification and message authentication. It probably is the first quantum protocol that can resist the man-in-the-middle attack by itself.

Quantum no-key protocol with inherent identification

Li Yang, Lei Hu

Various protocols of quantum cryptography has been presented. Some of them can be used to transmit secret messages directly. In this letter we present a new kind of quantum cryptography protocol for direct transmission of classical and quantum messages based on Shamir's generic protocol on classical message encryption. Though Shamir's original idea has only realization of computational security and falls to middle-man attack, our protocol is theoretically secure based on properties of quantum entanglement and Boolean function, and can resist the middle-man attack.
