Automatic Dependent Surveillance Broadcast (ADS-B) is the standard for aircraft surveillance and has been required on almost all aircraft within the National Airspace System since 2020. Data transmissions from ADS-B transponders are non-encrypted and, as a result, pose a variety of safety and security risks. Prior research has been conducted that provides solutions for retrofitting ADS-B systems with FPE (format-preserving encryption) algorithms. These require safe key distribution protocols to create the keys between parties. Classical key distribution protocols have been proposed and recently tested with some promise. However, with the rise of quantum computing, there is also a need for protection from future quantum threats. This paper explores the implementation of a quantum key distribution (QKD) protocol for the key generation of ADS-B transmissions using an FPE encryption algorithm with both free-space and optical links for air and ground distribution. This creates a level of security bounded by the laws of physics, as opposed to proposed key distribution methods, which are vulnerable to being hacked by both quantum and classical algorithms. Coupled with creating the protocol, a simulation is created to visualize the approach. This research stands to benefit all aircraft, national and international, that implement the ADS-B system, creating an increased sense of security, safety, and order in the air.
The project “Quantum Cryptography for Secure Messaging” aims to create a highly secure communication system using the BB84 protocol, a key method in quantum key distribution. As traditional encryption systems face growing threats from cyberattacks and future quantum computers, this project provides a future-proof solution for message encryption. It uses simulated quantum bits (qubits) to generate secret keys based on quantum mechanics, ensuring that any eavesdropping attempts can be detected instantly. The process involves encoding binary data into quantum states, securely exchanging keys, and applying them for symmetric encryption of messages. Key features include real-time key generation, automatic encryption and decryption, and intrusion detection. The expected outcome is a working prototype of a secure messaging system that can resist both current and emerging security challenges, highlighting the potential of quantum cryptography as a foundation for the next generation of digital security.
Quantum cryptography using the BB84 protocol is at the forefront of modern secure communication. This paper emphasizes on BB84 protocol and its role in secure key distribution utilizing the Qiskit libraries in Python to simulate Quantum Key distribution (QKD). This QKD is then applied to the One-Time Pad algorithm for message encryption and decryption. Ensuring data confidentiality and integrity and is difficult due to advanced cyber threats and the potential of quantum computing to undermine traditional cryptographic methods. Current encryption techniques are susceptible to quantum related attacks, risking the decryption of sensitive data. Alice (sender) and Bob (receiver) use classical encryption to communicate but eavesdropper Eve with quantum capabilities, can potentially decrypt their messages. This vulnerability affects critical data security in finance, healthcare, and national security, making robust cryptographic solutions essential for maintaining trust and safety in digital communications. Our work emphasis the utilization of the quantum key generated by employing the BB84 protocol with the help of Qiskit library in python as cipher text in the process of one time pad encryption and decryption. This encrypted data dispatched between the sender and receiver to ensure maximum security, confidentiality and integrity over the period of communication.
The rapid advancement of quantum computing poses a serious threat to traditional cryptographic systems such as RSA and Elliptic Curve Cryptography (ECC), which rely on computational difficulty for security. Quantum algorithms like Shor’s and Grover’s have the potential to break or weaken these methods, putting modern communication systems at risk. To address this challenge, this work presents a quantum-safe com-munication framework that combines the BB84 Quantum Key Distribution (QKD) protocol with Post-Quantum Cryptography (PQC) techniques, aiming to ensure secure data exchange in the presence of quantum-capable adversaries. In this system, the BB84 protocol is simulated to enable secure key exchange between two parties over a virtual quantum channel. The generated key is refined through processes such as basis matching, error correction, and privacy amplification using SHA-256 to ensure reliability and secrecy. For secur-ing communication, One-Time Pad (OTP) encryption is used alongside HMAC-SHA3-256 to provide both confidentiality and message integrity. Additionally, file encryption is handled using the XChaCha20-Poly1305 algorithm, selected for its efficiency and strong protection against potential vulnerabilities like nonce reuse. To further enhance security, the framework integrates a hybrid key management approach using the Kyber-512 Key Encapsulation Mechanism (KEM) combined with a Key Deriva-tion Function (KDF), merging classical and quantum-resistant techniques. Experimental results demonstrate the effectiveness of the system, achieving a Quantum Bit Error Rate (QBER) of 2.5% and successful performance in both message and file en-cryption. Overall, this work contributes toward the development of practical and resilient communication systems designed for the emerging quantum era.
Quantum Key Distribution (QKD) protocols offer a revolutionary approach to secure communication, leveraging the principles of quantum mechanics to enable theoretically unbreakable encryption. This comprehensive review examines the security and efficiency of various QKD protocols, including BB84, E91, and Continuous Variable QKD. We analyze the fundamental principles underpinning these protocols, their implementation challenges, and the practical considerations for real-world deployment. Special emphasis is placed on the security proofs of QKD, addressing potential vulnerabilities such as photon number splitting attacks and detector blinding attacks. Additionally, we explore the efficiency of QKD systems in terms of key generation rates, distance limitations, and integration with existing communication infrastructures. Recent advancements in QKD technology, including satellite-based QKD and quantum repeaters, are also discussed. Our findings highlight the critical role of QKD in future-proofing communication security and the ongoing efforts to enhance its practicality and scalability. This review aims to provide a detailed understanding of the current state of QKD protocols, offering insights into their potential to transform secure communications in the quantum era.
As the digital front becomes our new frontier, and digital data becomes increasingly vulnerable to highly sophisticated cyber attacks, conventional encryption approaches may no longer be sufficient to withstand a quantum attack. The focus of this work is to deploy a simulation of the BB84 protocol, one of the first Quantum Key Distribution (QKD) protocols developed by Charles Bennett and Gilles Brassard in 1984. The simulation involves two communicating parties, Alice and Bob, with Bob creating a secret keys generated cryptographically and sending it reliably over to Alice using quantum bits, or qubits. By leveraging quantum mechanics, this protocol ensures that any interception can be identified, thus bolstering both the integrity and confidentiality of the key exchange through scientists' understanding of superposition and the no-cloning principle. In the simulation, the potential of quantum communication to achieve secure key distribution over an insecure channel is demonstrated. Differently from traditional encryption protocols, QKD guarantees security not on computational but on physical basis. The aim of this paper is to show the feasibility and robustness of the BB84 protocol for actual cryptographic applications. This models the protocol between Alice and Bob, which paves the way for quantum-proof encryption systems and is a relevant step towards next generation cyber security.
