Abstract The transition to sixth-generation (6G) wireless networks demands cryptographic frameworks that simultaneously satisfy sub-millisecond latency constraints and resilience against quantum-capable adversaries; requirements that neither conventional quantum key distribution (QKD) nor emerging post-quantum cryptographic (PQC) schemes adequately address in isolation. This paper presents the Quantum Burst Protocol (QBP), a novel quantum-lite encryption scheme that replaces traditional two-way QKD handshakes with stateless, one-way quantum entropy bursts, enabling submillisecond secure communication between mobile and edge devices with minimal quantum hardware (2-3 qubits). QBP introduces three principal innovations: (i)~stateless operation via transient quantum entropy extraction, eliminating continuous channel negotiation; (ii)~ephemeral key derivation through domain-separated one-way hash functions, providing built-in forward secrecy and resistance to harvest-now-decrypt-later attacks; and (iii)~optional quantum-authenticatable message tagging for integrity verification. I present a comprehensive protocol specification encompassing system architecture, cryptographic design, and formal security proofs under quantum adversary models. Performance evaluation demonstrates end-to-end latency of 0.15-0.20\,ms, well within 6G thresholds. A rigorous comparative analysis against QKD (BB84, E91) and NIST-standardised PQC algorithms (ML-KEM, ML-DSA) reveals that QBP uniquely occupies a design space combining quantum-derived entropy strength with symmetric-key efficiency. I further discuss deployment considerations for edge, IoT, and non-terrestrial network scenarios, and outline a roadmap for experimental validation on constrained 6G-class hardware.

The Quantum Burst Protocol (QBP) is a novel quantum-lite encryption scheme tailored for ultralow-latency 6G wireless environments. QBP replaces traditional quantum key distribution (QKD) with stateless, one-way quantum entropy bursts, enabling submillisecond secure communication between mobile or edge devices. Leveraging ephemeral key derivation and quantum-authenticatable tags, QBP provides quantum-resilient confidentiality, authentication, and forward secrecy with minimal (2-3 qubit) quantum capability. We present the protocol design, performance analysis (demonstrating sub-0.2ms latency), and a formal security proof that includes a detailed mathematical analysis of its security properties against quantum adversaries. QBP is shown to be theoretically sound and practically deployable on 6G-class hardware.

The evolution of sixth-generation (6G) networks brings unprecedented demands for security, performance, and global interoperability. With the advent of scalable quantum computing, traditional cryptographic schemes such as RSA and ECC are increasingly vulnerable, making Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD) essential pillars for securing future communication infrastructures. This paper presents a comprehensive study on the standardization, implementation, and evaluation of PQC and quantum communication protocols within the context of 6G networks. We examine algorithmic candidates endorsed by NIST, such as Kyber and Dilithium, and analyze their performance, entropy guarantees, and deployment feasibility across diverse 6G use cases. A four-stage implementation roadmap is proposed, covering cryptographic testing, hybrid protocol integration, quantum entropy provisioning, and lifecycle cryptographic agility. Our evaluation framework introduces metrics for quantum resilience, protocol interoperability, energy efficiency, and compliance with ETSI, ITU, and IEEE standards. The paper also highlights key technical challenges such as latency overheads, entropy synchronization, and cross-domain cryptographic translation and outlines open research directions for scalable, secure, and sustainable deployment. By aligning cryptographic innovation with international standardization, this work contributes toward building a quantum-resilient, interoperable, and future-proof 6G ecosystem. The key results include handshake latency, which is 95 ms, entropy quality is 96%, interoperability 90 and the compliance score is 92%.
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 deployment of 5G and emerging 6G networks introduces significant security challenges for Internet of Things (IoT) ecosystems comprising billions of heterogeneous devices, including resource-constrained endpoints, more capable embedded controllers, gateways, edge nodes, and network infrastructure. At the same time, the long-term security of widely deployed public-key cryptography is challenged by advances in quantum computing, motivating migration toward standardized post-quantum key-establishment and digital-signature mechanisms. This comprehensive, evidence-based review classifies cryptographic mechanisms for wireless IoT in 5G and beyond across lightweight symmetric cryptography, post-quantum cryptography, privacy-preserving encryption, and adaptive security. The literature-reported implementation results are compared with explicit attention to heterogeneous hardware, memory, energy, communication, and latency constraints. Lightweight symmetric mechanisms remain relevant for constrained data protection, while standardized post-quantum mechanisms such as ML-KEM and ML-DSA address quantum-vulnerable public-key functions and generally introduce larger keys, ciphertexts, signatures, certificates, or protocol messages. This review therefore emphasizes interoperability, firmware upgradability, crypto-agility, and lifecycle management rather than physical device-size growth. A conceptual three-phase roadmap for 2025–2035 is presented in which quantum-vulnerable public-key mechanisms are progressively supplemented and, where appropriate, replaced by hybrid classical–post-quantum and then post-quantum-capable architectures, while standardized symmetric/lightweight protection remains in use where it satisfies application requirements. The roadmap dates are planning intervals rather than universal adoption forecasts.
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.
