The development of quantum computers will provide modern cryptographic systems with a practical computing infrastructure, yet the number-theoretic assumptions these systems are built on poses an acute security risk at this juncture, especially when Shor and Grover’s algorithms are considered. In this article, we present QRC-Stack (Quantum Resilient Cryptographic Stack): A modular architecture for post quantum about cyber resilient communication in current and next generation infrastructures of the internet. QRC-Stack combines lattice-based and hash-based schemes with transport layers and key management to guarantee data integrity, confidentiality, and authenticity within classical networks as well as software-defined networks. The architecture of QRC-Stack is enhanced by incorporating hybrid key exchange models that integrate classical (e.g., ECDH) and post-quantum (PQ) cryptography; Kyber and Dilithium from NIST PQC finalists to sustain legacy interoperability while advancing resilience to future threats in quantum networked environments The newly proposed QRC-Stack model includes three interrelated parts that together improve the security and flexibility of cryptographic communication within a quantum-threat context. Starting with the key management layer for quantum-aware systems (QKML), it incorporates a session key distribution system that the quantum cryptography foe cannot breach. Furthermore, the Adaptive Cipher Suite Negotiation (ACSN) injects a more node centric, risk-adaptive model in whereby selection of a cryptographic suite from a pool of available options is done dynamically where the suit best optimizes contextual threat. In addition, Q-Protect Transport Module enables seamless alignment with pre-existing transport protocols such as TLS/IPSec and QUIC or SD-WAN tunnels with limited overhead footprint. Emulation testing on SDN testbeds and active WAN environments showed that QRC-Stack sustained enterprise-class encryption throughput while adding latency overhead less than eight percent. Moreover, this hybrid architecture gives forward secrecy and stronger resistance to quantum-enhanced man-in-the-mid solar attacks with faster key refresh rates. QRC-Stack also outperformed classical TLS 1.3 alongside other variants of Transition Post Quantum Cryptography’, claiming steadfast post-compromised security while surpassing baseline models in adaptability, resilience, and versatility making it ideal for next-generation network backbone design. This information reconfirms QRC-Stack's supurb strength as an extensible multi layered blanced framework solution for communication systems in layers form situated in scenarios involving surveillance from powerful post-quantum adversaries. It helps to control the move toward safely moving quantum national, enterprise, and IoT networks from cryptographic systems built for surveillance heavy environments with minimal changes to current infrastructure.

The rapid evolution of communication networks, driven by the expansion of heterogeneous environments such as 6G, Internet of Things (IoT), and edge computing, has exposed a critical research gap in the lack of unified frameworks that jointly address intelligent network control and quantum-resilient security. Existing networking protocols were originally designed under static configurations and classical security assumptions, making them increasingly inadequate for dynamic, large-scale, and intelligent infrastructures exposed to quantum-enabled threats. At the same time, the emergence of Quantum Computing (QC) introduces severe security risks, as widely used cryptographic mechanisms supporting protocols such as Transport Layer Security (TLS) and Internet Protocol Security (IPsec) become vulnerable to quantum attacks. This paper presents a structured survey based on a systematic classification of recent literature across AI-enabled networking, Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and protocol-level integration approaches. The review categorizes existing works into AI-driven network optimization, quantum-resilient security mechanisms, and hybrid AI–QRC architectural frameworks, enabling a unified comparison of design strategies and deployment models. Furthermore, this survey analyzes how Artificial Intelligence (AI) techniques enable autonomous network operations while Quantum-Resilient Cryptography (QRC) approaches provide post-quantum security guarantees, highlighting their complementary roles in next-generation network design. The study further synthesizes key findings for a tightly coupled AI–QRC co-design, which remains an open challenge due to mismatched assumptions in control latency, cryptographic overhead, and protocol adaptability. Additionally, this review emphasizes the need for integrated frameworks that combine intelligence and quantum security to develop adaptive, scalable, and resilient network protocols for the post-quantum era.
As the digital landscape evolves, the reliance on cloud computing for critical infrastructure across various sectors highlights the need for robust security mechanisms to protect sensitive data from emerging cyber threats, particularly those posed by quantum computing. Traditional cryptographic systems, while currently effective, are vulnerable to quantum attacks, necessitating the development of quantum-resistant solutions. This research introduces the Quantum-Resilient Cryptographic Framework (QRCF), a hybrid, adaptive cryptographic framework designed to safeguard cloud environments against both classical and quantum threats. The QRCF integrates lattice-based Kyber and code-based McEliece algorithms, offering a comprehensive and scalable solution for secure data storage, management, and transmission. Key contributions include the development of a dynamic security management layer that adapts to real-time threat analysis, ensuring continuous protection against evolving threats, and the implementation of robust post-quantum cryptographic methods that maintain high performance and low computational overhead. Quantitative analysis shows that the QRCF maintains a high throughput of 420 MB/s for encryption and 400 MB/s for decryption under normal operations, with latency as low as 3.2 ms and 3.6 ms, respectively. The framework exhibited strong resistance to various attack models, with success rates of 1.0% for brute-force attacks, 1.875% for MITM attacks, 0.833% for side-channel attacks, and 1.6% for replay attacks. Against quantum threats, the QRCF showed no vulnerability to Shor’s Algorithm and a minimal success rate of 0.667% for Grover’s Algorithm. The framework’s design ensures seamless integration with existing cloud infrastructures, providing practical migration strategies to quantum-safe cryptography without disrupting operational workflows. By addressing key research gaps in quantum-safe cloud security, this study contributes significantly to the field, offering a robust, scalable, and efficient cryptographic solution that enhances the security and operational performance of cloud environments in the face of advancing quantum computational capabilities.
The rapid progress of quantum computing now poses a substantial security risk to the information infrastructures of various nations, which are fundamentally reliant on classical cryptographic systems. Encryption algorithms such as RSA, ECC, and, notably, Satyamani’s, Shor, and Grover algorithms are vulnerable to quantum attacks; indeed, these algorithms can compromise code creation and encryption protocols within seconds when subjected to powerful quantum computing devices. In response to this emerging threat, this paper presents the design and evaluation of a quantum-resilient cryptographic protocol suite intended for national information systems security. The proposed version integrates lattice-based key exchange and hash-based digital signatures, rendering it post-quantum and compatible with the existing Public Key Infrastructure (PKI) and network protocol stack. Formal security analysis and performance evaluation were conducted using simulated nationwide network environments. Experimental results demonstrate that the proposed scheme achieves a computational latency reduction of up to 45% compared to baseline post-quantum algorithms, while maintaining high resilience against both classical and quantum adversaries. The scalability test indicates that quantum-resilient cryptography can be deployed across various government apparatuses, promoting national cybersecurity and digital autonomy, while maintaining security and interoperability
Currently available cryptographic algorithms such as the RSA, Diffie-Hellman and the ECC are used in securing most Internet communications across the Internet. Theoretical quantum algorithms (and the Shor algorithm in particular) were demonstrated to be able to efficiently break that type of classical cryptography as soon as large-scale quantum computers are developed. To handle this new emerging security problem, PQC has been proposed as a class of cryptographic algorithms that is resistant to both quantum and classical attackers. It is a research paper offering and experimentally implementing a hybrid PQC-TLS protocol in a heterogeneous network architecture which includes edge computing devices and cloud computing and IoT devices. The suggested architecture integrates both lattice-based CRYSTALS-Kyber key encapsulation scheme and CRYSTALS-Dilithium digital signature scheme in the TLS 1.3 handshake without being interoperable with the older ECC-based key exchange schemes. Five measures of performance that included handshake latency, CPU consumption, memory consumption, bandwidth overhead and energy consumption were analyzed in detail through experimentation. The experiments were conducted using in Iot, edge and cloud nodes under controlled conditions that were repeated a number of times to give reliability in the statistics. The results indicate that the integration of PQC has moderate overhead (mean increase in latency about 1517) and decent computational and energy requirements. Another method of resisting popular attacks on networks like as the man in the middle, replay, and downgrade attacks, is security validation. The findings indicate that quantum resilient secure communication migration to a heterogeneous distributed infrastructure can be practically and scalably provided using hybrid PQC-TLS protocols. Statistical analysis including standard deviation and 95% confidence intervals was performed to validate the reliability of the results.
Quantum computing is rapidly approaching a stage where classical cryptographic systems, particularly RSA, ECC, and Diffie–Hellman, will no longer provide adequate security for critical infrastructure. The emergence of Shor’s and Grover’s algorithms introduces unprecedented vulnerability to national cyber-defense ecosystems, underpinning power grids, transportation, military communications, and banking systems. This paper presents a unified post-quantum cryptographic (PQC) security framework integrating lattice-based primitives, hybrid key-exchange mechanisms, and secure orchestration for resource-constrained operational-technology environments. The proposed architecture leverages NIST-recommended schemes, including CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+, to ensure long-term confidentiality, integrity, and interoperability across legacy and modern control environments. A defense-in-depth trust-fabric is introduced to protect critical data flows across edge controllers, automation PLCs, substations, cloud-SCADA gateways, and defense communication systems. Performance evaluation demonstrates a 39.4% reduction in key-exchange latency, 46% faster authentication cycles, and zero-downtime cryptographic transition capability. Our findings position this framework as a practical migration blueprint supporting national PQC readiness and cyber-resilience mandates.
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.
