Abstract

Quantum cryptography and quantum computing explore the physics and principles of randomness achieved through quantum mechanics. The aim of quantum cryptography is to transfer data from the sender to the receiver without any information loss, error, or violation of the needed security aspects. Ideally, the data should be transferred with basic standards like Confidentiality, Integrity, and Availability (CIA). Also, other services like authentication, authorization, access control, digital signatures, etc. need to be implemented depending on the requirement of the application. For all these services, random numbers are required to be used as nonces, session keys, identifiers, initialization vectors, seed values, etc. This work primarily focuses on generating random numbers using the Quantum Key Distribution (QKD) as a parallel benefit. BB84 and Six State Protocol (SSP) are the protocols used in Quantum Key Distribution (QKD). In this work, these protocols are simulated. The security levels of these protocols are analyzed based on the parameters like randomization and probability. The protocols are implemented in Qiskit software. Filter arrangement plays an important role in Quantum Cryptography. This offers an additional axis compared to the BB84 protocol. The approach thereby improves the randomization in SSP protocol. The comparison of both protocols shows that the SSP protocol gives better randomization when compared to the BB84 protocol.

The unique feature of QKD assures eavesdropping detectable during quantum communications which is fascinating for a high-level secure environment.Most of the traditional cryptographic methods which we use currently are based on mathematical scheme or Computational complexity theory which are not completely safe. Using quantum cryptography has been achieved extensive steps in communication security establishment. As the information Unit has been changed from “bit” to Quantum bit (Qubit), a new element has been offered that can guarantee the shared information confidentiality between parties. The confidentiality of system is established via exchanging a secret key through a channel of quantum, the key which we use for encrypting the shared data.

Quantum Key Distribution: Security Analysis of BB84 and E91 Under Realistic Attack Models

Bjursten, Sara

Cryptography is crucial to protect sensitive data. Traditional cryptography relies on mathematical difficulty to secure valuable data against intruders. However, with the rise of quantum computers, these assumptions are threatened as quantum computers can process information much faster. The security models need to be upgraded to withstand quantum computers. RSA and ECC, two common asymmetric cryptosystems, have been upgraded using post-quantum cryptography (PQC). Another solution might be to leverage the principles of quantum mechanics to ensure secure communication. The most common application of quantum cryptography is quantum key distribution (QKD), which solves the key exchange problem using quantum physics, complementing conventional cryptographic techniques by enabling secure key generation, while classical methods remain necessary for authentication and protocol implementation. QKD is secure in theory, but practical implementations often differ from theory due to imperfect devices. An intruder can find loopholes and vulnerabilities to attack the QKD systems and jeopardize its security. In this thesis, current knowledge of these attacks has been reviewed and simulated on two different QKD protocols. The simulations highlight the importance of researching the attacks and implementing countermeasures.

All traditional cryptographic algorithms used in the network communication environments, relied on mathematical models and computational assumptions, are actually unsafe and apt by many attackers (quantum and man-in-the-middle attacks). Therefore, nowadays Quantum Key Distribution (QKD) promises a secure key agreement by using quantum mechanical systems. QKD becomes a significant trend of new cryptographic revolution. This paper explains how cryptography exploits the quantum mechanics in order to achieve an encryption/decryption process. Additionally, this paper provides a standard simulation for QKD-BB84 protocol and describes improvement key generation and key distribution mechanisms. Then, validation, results and efficiency of BB84 protocol are presented using different security configurations. Finally, our results indicated that the QKD is susceptible to corporate with different security applications and achieve the key availability for such applications. However, it suffers from the higher rate of authentication cost.

Quantum Cryptography and Quantum Key Distribution

Chindiyababy, Ramkumar Jayaraman, Manoj Kumar

Quantum cryptography provides secret communication, which offers various security factors like confidentiality, integrity, and authentication assurance based on the law of physics. The law of physics states that quantum computing can also be applied into the communication sector, which is particularly in the field of cryptography. Then quantum can significantly distribute the data securely by applying quantum key distribution (QKD), quantum key sharing, etc. In the classical cryptography, it is difficult to compute secret keys using security concepts like key exchange and authentication, etc., and it fails to provide adequate protection during data communication as it needs some effective computation in terms of security. The lack of security in the data communication can be overcome by using the concept of quantum computing. Generally, in quantum computing, elementary quantum systems like polarized photons are used to transmit digital information based on the principle of uncertainty as it gives rise to a significant phenomenon of effective security in terms of communication compared to existing concepts related to cryptography. In quantum computing, the detection ratio for identifying the data which are sent through a communication channel is more difficult as it uses qubits and photons to represent the data that are sent. Quantum channels are used to distribute the information between two users as it passes through the unprotected classical channels as it is unknown to anyone else. Assuming that Alice and Bob use a latent noise channel to send a key, reconciliation is the process of correcting errors between Alice and Bob’s version of the key. This is done by public discussion, which leaks some information about the secret key to an undercover. This chapter gives a discussion on QKD concepts as it helps to provide a secure communication, where the information is broadcasting through a quantum channel. Finally, the various existing quantum protocols are described in relation to some security measures based on QKD, and the standard QKD protocol of BB84 is discussed.

Classical cryptographic systems are increasingly challenged by advances in computing power and new algorithmic techniques, particularly with the rise of quantum computing, which threatens the security of current encryption methods. This has spurred interest in quantum-resistant cryptography, aimed at creating algorithms that can withstand attacks from quantum computers. Traditionally, secure key transport over alternate channels has been a significant challenge, but quantum mechanics offers a solution. Quantum Key Distribution (QKD) is a revolutionary method for secure communication that leverages quantum principles. Unlike traditional methods, QKD provides unconditional security, with key security ensured by the laws of physics rather than computational difficulty. The BB84 protocol, introduced in 1984 by Bennett and Brassard, is a leading QKD scheme known for its simplicity and effectiveness in generating eavesdropping-resistant cryptographic keys. It facilitates secure key transport over alternate channels. This documentation aims to advance QKD security by practically implementing and analyzing the BB84 protocol. Through detailed theoretical analysis, simulation studies, and experimental validation, the practical impacts, and limitations of BB84-based QKD systems are examined. Additionally, a practical implementation of quantum key distribution using a sudoku key demonstrates the process's simplicity and effectiveness. These findings are expected to pave new paths in the field of cryptanalysis in the emerging Quantum Age.
