Wireless Body Sensor Networks (WBSNs) have rapidly developed to allow real-time health monitoring and remote medical diagnostics with better patient care. However, due to the sensitive nature of the data transferred within WBSNs, more integrated security mechanisms are mandatory, especially against possible attacks by both classical and quantum adversaries. The developments in quantum computing may break the conventional encryption schemes, so it is very important to explore quantum-resistant systems. The paper proposes a new scheme for lattice-based high-security authentication in WBSNs. Lattice-based cryptography provides post-quantum security as it has inherent resistance against quantum attacks and assumptions about the hardness of the computational problem, especially the Learning with Errors problem and the SVP. The architecture proposed strengthens defenses against man-in-the-middle, impersonation, and eavesdropping attacks by authenticating and ensuring that a safe key exchange takes place and that data integrity is achieved. It analyzes the performance, security overhead, and energy economy of LBQC to make sure it is appropriate for such low-power, low-resource contexts. The experimental outcomes validate the applicability of this technique, highlighting how well it will protect WBSNs against attacks from methods developed by quantum computing, and, at the same time, the system will remain resilient and the data confidential.

With the fast-paced development of quantum computing, classical cryptographic techniques are under severe security threats, prompting the need for post-quantum cryptographic mechanisms for secure data exchange in next-generation network communications. Post-quantum cryptography seeks to protect sensitive data against quantum attacks to provide long-term data confidentiality. But all current cryptographic techniques, including RSA and ECC, are susceptible to quantum algorithms like Shor's algorithm, which can factor large integers efficiently and break discrete logarithm problems, making classical cryptography useless. There is thus a pressing need for quantum attack-resistant encryption mechanisms. To meet these challenges, we introduce the Lattice-Based Cryptography with Hybrid Key Exchange (L-CHKE) framework, which combines lattice-based encryption with a hybrid key exchange mechanism. Lattice-based cryptography provides quantum resistance because it is based on hard mathematical problems such as Learning with Errors (LWE), which provides greater security and efficiency. The designed L-CHKE algorithm strengthens secure key distribution and authentication for next-generation networks, especially for applications needing strong security like financial transactions, IoT, and military communications. Experimental results verify that L-CHKE noticeably boosts computational efficiency by 98.45%, decreases key exchange latency by 42.56%, and guarantees robustness by 97.64% against quantum attacks, indicating it is an appropriate solution for post-quantum secure communication.
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.
The rapid proliferation of IoT technology has brought billions of devices into play that need to operate in a variety of diverse, resource-constrained environments. Secure authentication among these devices is a critical challenge, as traditional certificate-based public key infrastructures incur heavy computation and management overhead. Moreover, recent breakthroughs in quantum computing put at risk the security of classical cryptographic algorithms commonly used in IoT systems. This paper proposes a post-quantum certificateless authentication framework designed to address the efficiency-long-term security requirements of IoT environments. The proposed framework uses lattice-based cryptography to resist quantum-enabled adversaries while eliminating the need for digital certificates. The certificateless approach evades the problem of key escrow of identity-based cryptography and simplifies the key management process. A lightweight authentication protocol, which is suitable for constrained IoT devices, is developed. Security analyses prove that our proposed framework resists common attacks such as impersonation, replay, and man-in-the-middle attacks. The performance evaluation shows that our proposed framework reduces the communication and computational overheads compared with the traditional certificatebased authentication schemes. In this way, it is appropriate for large-scale and futureproof deployments of IoT systems.
Abstract In internet of things (IOT) healthcare systems, sensitive patient information is transmitted over the network to medical professionals. Numerous lightweight authentication protocols have been proposed; however, most of them remain vulnerable to various cyberattacks, allowing attackers to eavesdrop on or manipulate transmitted data. We examine several recently proposed lightweight authentication schemes for healthcare systems. Our security analysis demonstrates that these schemes remain vulnerable to malicious gateway attacks, desynchronization attacks, and key screw attacks. .To address these issues and ensure post- quantum security in healthcare IoT, we propose a post-quantum key establishment protocol based on lattice- based cryptography (LWE). the proposed scheme prevents the gateway from accessing both the secret keys and their parameters, thereby eliminating the possibility of malicious gateway attacks. The proposed protocol ensures user anonymity, forward secrecy, and resistance to impersonation, key screw, and desynchronization attacks.. The proposed protocol ensures secure and efficient establishment of three-round key establishment among entities . Our performance evaluation shows that the proposed scheme achieves lower computation and communication overhead compared to recent related works. The security of the protocol is thoroughly analyzed through informal reasoning, Burrows–Abadi–Needham (BAN) logic, and ProVerif, confirming its robustness and suitability for resource-constrained IoT-based healthcare environments.
Abstract Wireless Sensor Networks (WSNs) have been heavily deployed to facilitate continuous monitoring of their environments as they collect the necessary data which enable autonomous decision making or predictive control. As such, these networks have found applications in fields such as smart agriculture, military, industrial automation, and healthcare. During the message transfers among sensors or between sensors and mobile sinks, public communication channels are deployed. This exposes the collected data to a myriad of security threats such as tampering, eavesdropping, and replay. Although the recent past has witnessed the development of numerous security frameworks for this ecosystem, most of the current solutions are defenseless against threats such as session hijacking, side-channeling, ephemeral secret leakages and quantum attacks. In this paper, we leverage on lattice cryptography to develop an effective authentication framework for the WSNs. Formal security analysis confirms the robustness of our protocol under the Random Oracle Model (ROM). In addition, extensive semantic security analyses demonstrate the resilience of the proposed framework against typical attacks such as denial of service, key compromise and forgery. In terms of performance, we show that the developed framework incurs slightly lower computation and energy overheads when compared with its peers.
