In 6G-IoT music ecosystems, the development of quantum computers presents new dangers to privacy and security, as conventional cryptographic defenses cannot protect sensitive musical information. This paper proposes MUSI-PQC, a new post-quantum cryptographic protocol designed for reliability and trust in 6G-IoT music systems. MUSI-PQC, which is built upon the binary ring-learning with errors problem, optimizes the processing of musical data streams through polynomial superscalar acceleration and fast random number generation to ensure secure music transmission in 6G networks. The protocol achieves superior resource utilization across distributed edge nodes while maintaining high-security standards and trustworthiness metrics, demonstrating a 45% reduction in encryption time compared to existing approaches at the 140-bit quantum security level. Trust and security measurable trade-offs are shown with experimental results on emulated 8-bit 6G-IoT music systems where MUSI-PQC audio processing latency is kept lower than 0.8ms for 192kHz sampling rates, symbol recovery accuracy in constellation analysis is achieved at 99.7%, and private key demand is limited to 127 bytes revealing critical enhancements needed for dependable functionality in 6G-IoT music systems. The security assessment affirms MUSI-PQC’s reliability in protecting musical content during the quantum computing phase of 6G-IoT networks by confirming the protocol’s resilience against lattice attacks and other side-channel vulnerabilities, including timing, power, and fault injection attacks.

6G networks will require quantum-secure cryptography deployed across core infrastructure, edge nodes, resource-constrained IoT devices. Although post-quantum cryptographic (PQC) algorithms have been standardized by NIST, their practical deployability in bandwidth and latency limited wireless systems remains unclear. This paper presents a practical evaluation of NIST selected PQC schemes, including ML-KEM (Kyber), ML-DSA (Dilithium), and Falcon. Benchmarks conducted with OpenSSL and the OQS provider on heterogeneous platforms show that while computational performance is acceptable, ciphertext and signature size expansion significantly impact handshake reliability and bandwidth efficiency, particularly at the network edge. The results highlight key system-level trade-offs and motivate the need for PQC optimization and deployment-aware design for future quantum-secure 6G networks.
The evolution of 6G networks necessitates robust authentication and key agreement (AKA) protocols to counter emerging security challenges, particularly the threat posed by quantum computing. Existing 5G-AKA protocols remain vulnerable to user tracking, replay attacks, and false base station impersonation, while Elliptic Curve Cryptography (ECC) and RSA-based key exchanges face imminent obsolescence due to quantum attacks. This study examines the vulnerabilities of 5G-AKA and explores hybrid post-quantum cryptography (PQC) as a transitional security solution for 6G networks. We evaluate NIST-standardized PQC algorithms, focusing on their computational overhead, key size efficiency, and adaptability to heterogeneous network environments, including IoT and ultra-low latency applications. A comparative analysis of hybrid cryptographic schemes demonstrates that lattice-based (Kyber, Dilithium), hash-based (SPHINCS+), and code-based (BIKE, Classic McEliece) PQC techniques provide varying trade-offs between security, efficiency, and deployment feasibility. Furthermore, we propose a quantum-resistant 6G-AKA framework, integrating hybrid PQC, AI-driven trust mechanisms, and decentralized authentication to ensure scalability and interoperability. Experimental benchmarks highlight potential performance constraints, including latency in PQC-based key exchange and resource limitations in edge computing. Addressing these challenges requires the optimization of lightweight PQC implementations, formal security validation, and global standardization efforts. Our findings provide a roadmap for the secure transition to 6G authentication protocols, ensuring resilience against both classical and quantum threats.
The potential of the swift development of quantum computing is an extreme danger to the traditional cryptographic programs, and they are the foundation of the modern communication infrastructure. RSA and ECC are classical public-key algorithms that can be successfully quantum-attacked, in particular, Shor's algorithm can easily factor large integers and calculate discrete logarithms (Bernstein et al., 2017). The Post-Quantum Cryptography (PQC) has become the key to secure the next-generation communication networks against these threats, which relies on lattice problem-based algorithms, hash-based based algorithms, multivariate polynomials-based algorithms, and code-based cryptography. The paper examines the concepts, design, and implementation issues of PQC within current network infrastructure focusing on the secure transmission of data, authentication, and key management in the upcoming 5G and 6G networks. The approach will include the survey of existing algorithms of PQC, model the integration of protocol in the communication systems and test computational efficiency, security strength, and scalability. It has been found that PQC is suitable to protect network communications against quantum attackers, and achieves reasonable performance, though trade-offs can be seen in terms of computation overhead, key size, and latency. The research offers understanding to the researcher, network engineers and policy makers in order to adopt quantum resistant cryptography protocols to secure the confidentiality, integrity and authenticity of information in the future communication networks.
The evolution of 6G communication systems brings about unprecedented demands on ultra-reliable, lowlatency, wide-scale and end-to-end secure transmissions. At the same time, the emergence of quantum computing presents major risks for traditional cryptographic schemes, which will become unsecure for future communication infrastructures. This arti-cle introduces the first mathematically inspired architectural framework incorporating Post-Quantum Cryptographic (PQC) protocols into the 6 G design to facilitate secure and efficient communication in quantum-inimical scenarios. The framework successfully integrates them so that lattice-based cryptography and code-based signatures or multivariate polynomials with low complexity could work with one another to implement real-time confidential communication concurrently with the authentication and key exchange, while meeting the requirements of latency and bandwidth. We propose a three-layer architecture, crypto-graphic-agile and mathematically optimized, that operates at: physical, MAC and network layers and focuses on the energy efficiency, computational offloading and dynamic proto-col adaptation. In addition, the paper proposes a suite of new benchmarking metrics for QKD systems based on security, latency, and scalability, and conducts forward-looking numerical calculations under both classical and entirely quantum-safe and hybrid classical-quantum threat models. The results in this study have confirmed that the mathematically-based cryptographic modes can serve as 6 G architecture part, that can guarantee quantum resilient secure networking. The paper also points out open issues and research directions toward the efficient integration of PQC into upcoming wireless standards. Finally, this work provides the foundation framework for secure, ultra-reliable, and low-latency communication to be realized in the post-quantum 6G era.
Advances in the field of interconnected consumer and IoT devices have highlighted the vulnerabilities of conventional cryptography to quantum computing. This paper presents a new hybrid model of post-quantum cryptography (PQC) that provides a high level of assurance in the edge-IoT ecosystems. The model being proposed combines lattice-based methods, i.e., Kyber-786 and Dilithium-III, and an AES-GCM layer model. Moreover, a trust and key negotiation mathematical analysis brings to fore the resistance of classical and quantum attackers with module-LWE and ring-LWE assumptions. The Python-based simulation proves that the suggested method increases the throughput by 18.6% and reduces the latency by 22.4% in comparison to the conventional methods. Also, there is a reduction of energy consumption by 41.7% with the use of a hybrid design caused by the hardware-accelerated two-polynomial operations and an optimized offloading. The analysis has shown that the proposed solution satisfies the confidentiality, integrity, and authenticity with less than 7.3 ms overhead per transaction, and PQC can be used in IoT and consumer settings without compromising responsiveness and energy consumption.
The emergence of quantum computing seriously threatens the security of legacy cryptographic protocols in consumer electronics devices based on the Internet of Things (IoT). These are essential components of mission-critical infrastructures, such as industrial control systems, smart grids, and healthcare. In particular, this work examines how to strengthen the resistance of the IoT to classical and quantum-based cyberattacks by combining deep learning methods with post-quantum cryptography (PQC). To protect key exchange, encryption, and authentication processes in IoT-consumer devices, we will continue to use quantum-resistant cryptographic algorithms, including lattice-based, hash-based, and code-based cryptography. To provide real-time anomaly detection and response capabilities, we suggest a hybrid security framework combining PQC with deep learning-based intrusion detection systems. Our methodology ensures secure communications and data exchanges linked to quantum attacks in the future within IoT systems while leveraging continuous learning over time to allow Intrusion Detection System (IDS) models to adapt to new attack vectors. We suggest optimized algorithms for PQC solutions that are lightweight and suitable for deployment in edge computing nodes and Internet of Things devices, considering the resource-constrained IoT situations where PQC implementation would be difficult. Through comparative studies and simulations, we demonstrate how our integrated PQC-deep learning framework offers an improved IoT security solution that could safeguard vital systems in a world powered by quantum technology. The results shows the key generation time which is 12.5ms, encryption/decryption time 25.3ms, latency 18.7ms, throughput 5000 operations/sec and energy consumption 2.4mJ.
