Abstract

Abstract— This work presents quantum key distribution protocols (QKDPs) to safeguard security in large networks, ushering in new directions in classical cryptography and quantum cryptography. Two three-party QKDPs, one with implicit user authentication and the other with explicit mutual authentication, are proposed to demonstrate the merits of the new combination, which include the following: 1) security against such attacks as man-in-the-middle, eavesdropping and replay, 2) efficiency is improved as the proposed protocols contain the fewest number of communication rounds among existing QKDPs, and 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.

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.

Performance of integrated quantum and classical cryptographic model for password authentication

T. S. Thangavel, Aravind Krishnan

The security of quantum cryptography relies on the foundations of quantum mechanics, in contrast to traditional public key cryptography which relies on the computational difficulty of certain mathematical functions, and cannot provide any indication of eavesdropping or guarantee of key security. The proposal present in this work develops a quantum key distribution model to safeguard security in large networks, in the directions of classical cryptography and quantum cryptography. Two three-party Quantum key distribution are used in this model, one with implicit user authentication and the other with explicit mutual authentication, are proposed to demonstrate the merits of the new combination. The performance of Quantum Key Distribution (QKD) systems have notably progressed since the early experimental demonstrations. The current evolutions in QKD research indicate that the pace of this progression is very likely to be maintained, if not increased, in the future years. In parallel to these improvements of QKD techniques, commercial products are also being developed, making QKD deployment a feasible alternative for securing real data networks. Deployment of a real QKD network is however far from being straightforward. It requires development of a network architecture connecting multiple users that may possibly be very far away from each other. Considering the fact that the existing QKD links are only point-to-point, and intrinsically limited in distance, deployment of a practical QKD network structure is a nontrivial problem. The proposed work describes the proposed architecture for a QKD network specify the requirements relevant to the network design, protocols, and services. The objective of this specification is to define the major components and their main features The proposal provides security against such attacks as man-in-the-middle, eavesdropping and replay. It also improves the efficiency of the quantum key distribution which contains the fewest number of communication rounds among existing Quantum key distributions. In this model two parties can share and use a long-term secret (repeatedly). To prove the security of the proposed schemes, this proposed model provides a primitive called the Unbiased-Chosen Basis (UCB) assumption with the quantum key in angular positions.

Secure Communication Using Two Party Authenticated Quantum key Distribution Protocols

S. Venkatramulu, S. Veena

This work presents quantum key distribution protocols (QKDPs) to safeguard security in large networks, efficiency is improved as the proposed protocols contain the fewest number of communication rounds and two parties can share and use a long-term secret Key. Quantum cryptography is basically based on a trusted channel in communication between two parties compared to classical channel. Recently, Quantum Key Distribution (QKD) has become more secure transmission method used to transmit secret key between two legitimate parties. This paper discusses the implementation of (QKD) protocol with the existence of an eavesdropper. The implementation simulates the communication of two parties who wish to share a secret key with the existing of eavesdropper. The existing of eavesdropper is simulated with two kinds of attacks, which is used as parameter to measure the length of final key agreed by both authenticated parties at the end of the communication.

SECURITY USING QUANTUM KEY DISTRIBUTION PROTOCOLS (QKDPs)

D. N. Kartheek, Mohit Kumar, Mohit Kumar

Abstract — Most cryptographic mechanisms such as symmetric and asymmetric cryptography, often involve the use of cryptographic keys. However, all cryptographic techniques will be ineffective if the key distribution mechanism is weak. Quantum Key Distribution or Quantum Cryptography is attracting much attention as a solution of the problem of Key Distribution; QKD offers unconditionally secure communication based on quantum mechanics. This work presents quantum key distribution protocols (QKDP) to safeguard security in large networks, ushering in new directions in classical cryptography and quantum cryptography.
