With the rapid advancement of Low Earth Orbit (LEO) satellite constellations, ensuring the security of satellite-to-ground communication has become a critical concern. Traditional cryptographic techniques, while effective against classical attacks, face increasing threats from quantum computing. This paper proposes a quantum key secure transmission method tailored for LEO satellite-ground communication scenarios. The method integrates quantum key distribution (QKD) with dynamic channel estimation and orbital mobility prediction to support secure and low-latency key handshakes between satellites and ground stations. A hybrid encryption strategy is introduced, where QKD-generated keys are used to refresh symmetric session keys in real time, significantly enhancing resistance to eavesdropping and man-in-the-middle attacks. Simulation results demonstrate that the proposed method ensures stable key distribution under Doppler-shifted and intermittent link conditions, achieving improved secrecy capacity and resilience against quantum-level adversaries. This work provides a viable and scalable quantum-safe communication solution for future secure satellite networks.
This paper presents a U.S.-focused design and evaluation of CRYSTALS-Kyber-based encryption protocols tailored for secure satellite-to-ground communications. With the emerging threat posed by quantum computing to traditional public-key cryptography, the integration of post-quantum encryption schemes such as Kyber has become critical for safeguarding space-based assets. The study evaluates the Kyber protocol in simulated orbital conditions, measuring handshake efficiency, encrypted throughput, packet retransmission resilience, CPU and memory consumption, session recovery latency, and scalability. Kyber demonstrated superior performance in reconnection speed, loss recovery, and session scalability compared to RSA and ECC baselines, while maintaining acceptable computational loads for deployment on both ground stations and small satellite platforms. The protocol’s resilience to variable latency and degraded signal environments confirms its suitability for low-Earth orbit (LEO) communication profiles. Results support phased deployment in U.S. aerospace networks, beginning with mission-critical command links. This work contributes new empirical insights into the readiness of post-quantum cryptography for real-world space applications.
SIoT based on satellites is becoming a major concept to provide ubiquitous connectivity in remote and mission-critical applications. Nevertheless, inherent threats like low bandwidth, limited energy supply, and susceptibility to the long-range eavesdropping are serious security issues. Moreover, quantum computing also poses a threat to the traditional cryptographic algorithms such as the RSA and ECC. This paper came up with a Lightweight Quantum-Resistant Encryption Mechanism that will be applied in SIoT networks to solve these problems. The model is a hybrid of lattice-based CRYSTALSKyber key exchange with AES-GCM payload encryption to guarantee quantum resistance and efficiency. Optimizations that are hardware friendly, key compression and a hybrid encryption method are used to improve performance in low power satellite environments. Experimental evaluations show that the proposed scheme reduces energy consumption by 2835%, lowers key exchange time by approximately 40%, and maintains high data confidentiality and integrity under quantum threat models. The mechanism offers a scalable, future-proof, and secure solution for protecting satellite-based IoT communications.
This massive rate of expansion of the Internet of Things (IoT) has brought about an immediate demand of safer and efficient communication methods with the capacity to endure upcoming cyber threats of the quantum age. Conventional cryptographic keys like RSA and ECC are getting more susceptible to quantum attacks and thus quantum-proof modules should be developed. This study introduces a Quantum-Resilient Communication Protocol, a lightweight cryptography-authentication post-quantum cryptography protocol, an integration of lattice and AES-GCM encryption with HMAC-based authentication to enable more resource-constrained IoT devices to be amely secured. MATLAB and NS-3 were used to simulate the proposed protocol and the performance of the proposed protocol was compared to a traditional ECC-based IoT protocol. The findings indicated that QRCP had improvement in the latency, throughput and energy savings over 40 percent and it was found that QRCP resisted quantum attack of Shor and Grover. The results justify the practicality of integrating the post-quantum cryptographic exceptors in the IoT network and provide a scalable, energy-saving, and future-enabling paradigm of the secure communication in the quantum era of computational computing.
The rapid proliferation of Internet of Things (IoT) devices has revolutionized digital communication, yet it simultaneously poses unprecedented security challenges due to constrained device capabilities and increasing cyber threats. Conventional cryptographic techniques, while currently effective, are vulnerable to emerging quantum computing technologies that threaten to render classical encryption obsolete. This paper explores the integration of quantum-safe cryptographic techniques within IoT networks to ensure long-term confidentiality, integrity, and authentication. It examines post-quantum cryptographic primitives, including lattice-based, hash-based, multivariate, and code-based schemes, and evaluates their suitability for resource-constrained IoT environments. The study focuses on lightweight implementation strategies, balancing computational efficiency with robust security requirements. Simulation analyses demonstrate that properly optimized quantum safe protocols can provide resilient encryption, key exchange, and digital signature functionalities without overwhelming device resources. Furthermore, the integration of these techniques with IoT communication standards and secure network protocols ensures end-to-end protection across heterogeneous networks. Challenges such as latency, energy consumption, and scalability are addressed, highlighting the necessity of tailored cryptographic solutions for diverse IoT applications. The findings confirm that quantum safe cryptography is essential for future-proofing IoT networks, offering sustainable security measures that remain resilient against both classical and quantum adversaries, thereby supporting the continued expansion of secure and intelligent interconnected systems.
The rapid expansion of the Internet of Things (IoT) has introduced unprecedented cybersecurity challenges, as traditional cryptographic methods struggle to provide both efficiency and quantum resistance in resource-constrained environments. This research introduces Adaptive Quantum Cryptography (AQC), a novel security framework that integrates Quantum Key Distribution (QKD), Post-Quantum Cryptography (PQC), Quantum Random Number Generators (QRNGs), and AI-driven dynamic adaptation to safeguard IoT networks against evolving cyber threats. Unlike classical encryption techniques such as RSA and ECC, which are vulnerable to quantum attacks, AQC leverages quantum mechanical principles—such as superposition, entanglement, and the no-cloning theorem—to ensure provably secure key exchange and data encryption. The proposed AQC system dynamically adjusts cryptographic protocols based on real-time network conditions, computational resources, and threat intelligence, optimizing security without imposing excessive overhead. Experimental evaluations demonstrate that AQC achieves a 70% improvement in key exchange efficiency, a 50% reduction in computational load, and a 95% resilience rate against quantum attacks compared to conventional encryption methods. Additionally, the integration of QRNGs enhances cryptographic key entropy, while AI-driven anomaly detection enables proactive threat mitigation. This framework is particularly suited for next-generation IoT applications, including smart grids, autonomous vehicles, and industrial automation, where security, scalability, and energy efficiency are critical. By combining quantum-resistant algorithms with adaptive security mechanisms, AQC provides forward secrecy, resistance to quantum adversaries, and robust authentication, ensuring long-term protection for IoT ecosystems in the post-quantum era. The findings underscore AQC’s potential as a foundational security architecture for future quantum-safe IoT networks.
