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 growth of the Internet of Things (IoT) has connected billions of smart devices across healthcare, transportation, industrial automation, and smart home environments. While IoT has enhanced automation and data-driven decision-making, its widespread deployment has also increased the risk of cyberattacks. Conventional public-key cryptographic algorithms such as RSA and Elliptic Curve Cryptography (ECC) are vulnerable to future quantum computing attacks, particularly those based on Shor's algorithm. This paper proposes a Quantum-Resistant Cryptographic Framework (QRCF) for secure IoT communication using lattice-based cryptography integrated with lightweight authentication and efficient key management. The framework is designed to meet the computational limitations of IoT devices while ensuring long-term confidentiality and integrity. Performance evaluation demonstrates improvements in security resilience, authentication efficiency, and communication reliability compared with traditional cryptographic approaches. The proposed framework offers a scalable and future-ready solution for protecting IoT ecosystems in the post-quantum era.
The rapid expansion of Internet of Things (IoT) ecosystems has introduced significant security challenges due to resource-constrained devices, heterogeneous network architectures, and largescale connectivity. Traditional authentication and key exchange mechanisms, primarily based on classical cryptographic algorithms such as RSA and ECC, are vulnerable to future quantum computing attacks. The emergence of quantum algorithms, particularly Shor’s algorithm, threatens the long-term confidentiality and integrity of IoT communications. This paper proposes a Quantum-Resistant Authentication and Key Exchange Protocol specifically designed for secure IoT architectures. The proposed framework integrates post-quantum cryptographic primitives, including lattice-based key exchange mechanisms and hash-based authentication schemes, optimized for low computational overhead suitable for constrained IoT devices. The protocol ensures mutual authentication, forward secrecy, and resistance against quantum adversaries while maintaining minimal communication latency. Security analysis demonstrates robustness against replay, man-in-the-middle, and key-compromise attacks. Performance evaluation shows that the proposed solution achieves a balance between quantum security strength and resource efficiency, making it suitable for next-generation IoT deployments in smart cities, healthcare systems, and industrial automation.
With the transition of the world to quantum computing, existing cryptographic algorithms are more exposed, and strong post-quantum solutions are required. Lattice-based cryptography, specifically the Kyber512 algorithm, offers quantum-resistant security that can be utilized in low-resource environments, such as Internet of Things (IoT) devices. Existing key exchange techniques for IoT, including RSA and ECC, are susceptible to quantum attacks and tend to be computationally heavy for low-power devices. Such drawbacks render them inefficient in actual-world smart home solutions, where longevity and security efficiency are required. This research presents a new framework, Smart Home Device Communication Security using L-PKEX – a lightweight post-quantum key exchange algorithm based on Kyber512 - that bridges these gaps. L-PKEX is designed to facilitate the economic and secure exchange of keys among smart home gadgets (e.g., smart locks, sensors, controllers) by utilizing Kyber512. The new proposed L-PKEX approach is used to establish secure communication networks among smart home devices, hubs, or user interfaces. Experimental validation and simulations demonstrate that L-PKEX offers minimal computational overhead and reduced energy consumption while maintaining uncompromised security, compared to conventional approaches. Results prove that L-PKEX is an affordable and scalable solution towards providing quantum-resistant, secure smart home IoT communication.
The resource limitations of IoT nodes and the vulnerability of wireless channels to cyberattacks and snooping, the quick spread of Internet of Things (IoT) devices in wireless surroundings has created serious challenges to data security and privacy. The development of quantum computing, which can meritoriously crack classical encryption, is posing a growing threat to recognized cryptographic techniques like RSA and ECC. By applying concepts from quantum mechanics like predicament cloning, quantum cryptography, in particular Quantum Key Distribution (QKD), provides tentatively unbreakable security. In order to integrate lightweight quantum key exchange with traditional IoT communication protocols, this paper proposes a comprehensive Quantum Cryptography Framework (QCF) exactly designed for Wireless IoT networks. The framework is made to preserve energy efficiency while certifying forward secrecy, confidentiality, integrity, and authentication. A performance evaluation in terms of latency, throughput, and resistance to quantum attacks supports our discussion of the architecture, working mechanism, and implementation deliberations. The findings show that, when compared to traditional encryption methods, the suggested QCF greatly improves the security of wireless IoT systems, certifying resilience against oppositional models of the future.
To solve the issue of new security threats to the satellite-based IoT (Sat-IoT) networks introduced by quantum computing, this research intends to create a quantum-resistant communication protocol of the satellite category of networks (Sat-IoT).As novel low Earth orbit (LEO) satellite constellations emerge to enable the reach of global IoT networks, secure and flexible communication in the presence of quantum-capable adversaries constitutes the most important consideration.In the given study, the post-quantum cryptographic package (lattice-based encryption: Kyber-1024) is combined with the reconfigurable antenna system in order to perform enhanced two-level security.A new protocol suite is proposed combining a quantum-safe key exchange, physical-layer beam reconfiguration and integrity-aware adaptive link management.The model is an analytical model which is verified with satellite channel requirements utilizing LEO dynamics.The most important measures of performance are key compromise probability, signal-in-interference-plus-noise ratio (SINR), and encryption latency of simulated quantum attacks.The findings show that the suggested protocol can better the key compromise resistance levels by up to 82 percent than the conventional ECC-based or RSA-based protocols.The adaptive antenna subsystem will also increase the resilience of the links in a high interference environment by 45 per cent.These findings help find out that the cryptographic hardening, combined with antenna level adaptability, can improve the Sat-IoT network survivability in the quantum age tremendously.To sum up, this work looks promising as a similar work can eventually be employed to allow scalable and forward-compatible secure satellite-IoT communication and acts as a scalable anchor of future quantum-safe Sat-IoT implementations.
