A brief introduction of quantum cryptography for engineers

Bing Qi, Liping Qian, Hoi‐Kwong Lo

We present the fundamental principles behind quantum key distribution and discuss a few well-known QKD protocols. Bearing in mind that the majority of our readers are from engineering and experimental optics, we focus more on the experimental implementation of various QKD protocols rather than security analysis. Another important topic that is covered here is the study of the security of practical QKD systems.

Requirements Engineering for Integrating Quantum Key Distribution with Blockchain Systems

Quantum Key Distribution (QKD) represents an advanced cryptographic security technology which uses principles of quantum mechanics to confront the threat of quantum computing. Cryptographic protocols such as elliptic curve cryptography (ECC) alongside RSA serve as present blockchain key exchange methods yet they remain exposed to possible quantum computing damage. This research method employs grounded theory based on interviews with twenty blockchain engineers and cybersecurity experts to explore QKD and blockchain integration along with basic requirements needed to build a quantum-resistant blockchain framework. Systematic analysis of security expert opinions showed that achieving integration success depends on operational resilience, security infrastructure development and governance mechanism development. A complete framework to integrate QKD into blockchain key exchange protocols was created from these identified dimensions which enables smooth transition between hybrid cryptographic operations and Post-Quantum Cryptography (PQC) protocols. The research fills an essential theoretical-to-practical divide for quantum cryptography by creating implementation methods that support secure decentralized blockchain networks.

Modeling, Simulation, and Analysis of a Decoy State Enabled Quantum Key Distribution System

Ryan Engle

Abstract : Quantum Key Distribution (QKD) is an emerging technology which uses the principles of quantum mechanics to provide unconditionally secure key distribution. QKD systems are unique in their ability to detect an eavesdropper's presence and are being marketed for applications where high levels of secrecy are required such as banking, government, and military environments. QKD systems are composed of electrical, optical, and electrooptical components. Their design requires expertise across multiple disciplines including computer science, computer engineering, electrical engineering, information theory, optical physics, and quantum physics. This multidisciplinary nature makes QKD an ideal candidate for study using Model Based Systems Engineering (MBSE) Processes, Methods, and Tools (PMTs). The primary research goal is to gain understanding of the operation and performance of the QKD decoy state protocol through the use of MBSE PMTs. The main research contributions include development of a decoy state model, validation of the this protocol in a QKD system model implementation, and confirmation that application of MBSE PMTs are critical to the understanding and analysis of complex systems. This work presents the first known application of MBSE PMTs to analyze a QKD system and provides utility to system developers, designers and analysts who seek to quantify performance and security.
