A recent industry communication (King, 2026) reports that SEALSQ and WISeKey are advancing a Quantum Spatial Orbital Cloud (QSOC): a planned low-Earth-orbit constellation that would recast satellites from communications relays into trusted computing nodes combining post-quantum cryptography (PQC), quantum random-number generation (QRNG), digital identity, edge artificial intelligence, and secure machine-to-machine transaction. This article isolates the constitutive concepts of that communication, subjects each to theoretical enquiry, and compares the leading families of theory in the relevant fields—public-key cryptography after Shor, physical-layer quantum key distribution, hardware roots of trust, certified entropy, digital identity, edge/autonomous computation, and sovereign infrastructure. It then offers a prediction about the epistemology that arises once PQC ceases to be a laboratory primitive and becomes an orbital, physically gated, multi-assumption infrastructure. The argument is that 'post-PQC epistemology' is not merely the knowledge that certain lattice, hash, or code problems are hard. It is a hybrid onto-epistemic regime in which justified belief about secure communication is produced by the co-presence of (i) diversified mathematical hardness, (ii) certified physical entropy, (iii) hardware-bounded execution integrity, and (iv) jurisdictional claims over extra-territorial compute.

The advent of cryptanalytically relevant quantum computers (CRQCs) threatens the foundational mathematical hardness assumptions of contemporary public-key cryptography. In response, Post-Quantum Cryptography (PQC) has emerged, predominantly framed through an epistemic lens of "algorithmic substitution"—replacing vulnerable algorithms with quantum-resistant ones. However, for sovereign entities and developing digital infrastructures, this universalist approach is insufficient. This paper conducts a deep epistemic analysis of the shift toward layered architectural resilience, cognitive sovereignty, and cybernetic governance. It proposes a foundational set of normative principles for a sovereign PQC protocol and systematically compares ten competing theories in cryptography, digital sovereignty, and data architecture.

This seventh volume of the series establishes the first formal post-post-quantum taxonomy—a three-tier ontological and epistemological hierarchy that reclassifies all post-quantum cryptographic schemes according to the fundamental nature and justification of their security. The hierarchy progresses from computational (algorithmic hardness assumptions) through physical (thermodynamic, noise-engineered, and hardware-constrained irreversibility) to device-independent (information-theoretic guarantees independent of device implementation). Building directly upon the anatomical critiques, hybrid primitives (Vol II), QRAM-hardness (Vol III), parameterized adversary models (Vol IV), GKP-resistant countermeasures (Vol V), and NISQ empirical validation (Vol VI), we provide a complete reclassification of NIST PQC standards, hybrid protocols, and the novel primitives introduced across the series. Dedicated Mamun, SM (2026) ……………………………….1 Theoretical and Physical Boundaries of Lattice-Based Post-Quantum Cryptography: An Anatomical Critique of Post-Post-Quantum Taxonomy (Vol-VII) sections dissect the ontology (what security is) and epistemology (how security claims are known and justified) of each tier. K S C The taxonomy reveals that current lattice-based schemes remain anchored in the provisional computational tier, while the countermeasures developed in Vols III–VI elevate them into the physical tier. True device-independent security remains an aspirational frontier. Also available on Academia.edu: https://www.academia.edu/attachments/132771868/download_file?s=portfolio
The migration to post-quantum cryptography (PQC) is widely framed as an algorithmic substitution problem: replace RSA and elliptic-curve primitives with the module-lattice schemes standardised by the United States National Institute of Standards and Technology (NIST) as ML-KEM (FIPS 203) and ML-DSA (FIPS 204). This paper argues that such a framing constitutes a locks-versus-the-archive fallacy. Adversaries practising harvest-now-decrypt-later (HNDL) strategies have already rendered perimeter-centric defences obsolete; changing cryptographic locks does nothing to protect the exabytes of ciphertext previously exfiltrated. The true enterprise and sovereign challenge is architectural. Four coupled claims are developed. First, security must shift from network perimeters to data-level resilience through genuine crypto-agility—the capacity to hot-swap primitives across legacy lakes without breaking application programming interfaces, compliance pipelines or availability. Second, infrastructure is speciating into three physical forms: silicon halls for hot compute, molecular halls for deep archival storage, and sovereign caches as jurisdictional vaults. Third, as enterprises become agentic systems, the post-quantum transition becomes a crisis of memory integrity; vector indices must be decoupled from narrative payloads and every memory block must carry a post-quantum chain of custody if narrative poisoning is to be prevented.

This review provides a detailed anatomical dissection of Jung et al. (2026), a recent preprint that challenges the prevailing classification of lattice-based cryptography—particularly the Learning with Errors (LWE) paradigm—as unconditionally "post-quantum." The paper systematically interrogates LWE across computational complexity, information-theoretic thermodynamics, quantum error correction (QEC), and quantum learning theory, arguing that its security rests on transient physical and engineering bottlenecks rather than fundamental theoretical barriers. We evaluate the paper's structure, strengths, and limitations; situate its claims within at least ten competing models and theories in post-quantum cryptography (PQC); examine the ontological (nature of cryptographic security) and epistemological (justification KSCCN Mamun, SM (2026)…………………………………1 Theoretical and Physical Boundaries of Lattice-Based Post-Quantum Cryptography: An Anatomical Critique of Noise-Reliant Security in the Quantum Era (Vol-I) of security claims) dimensions of its central themes; and propose extensions and ideation pathways. While the work offers a provocative interdisciplinary synthesis, its conclusions remain largely speculative and do not constitute a practical break of standardized schemes. Nonetheless, it underscores critical gaps in the long-term robustness of noise-dependent PQC. Also available on Academia.edu: https://www.academia.edu/attachments/132758388/download_file?s=portfolio
The transition to post-quantum cryptography (PQC) based on the Learning with Errors (LWE) problem suffers from a critical epistemological gap: its security is predicated on transient computational bottlenecks, not information-theoretic permanence, making it vulnerable to mature quantum algorithms like Gottesman-Kitaev-Preskill (GKP) error correction. This critique argues that absolute quantum resilience requires a pivot to inherently hybrid architectures that systematically combine LWE's computational efficiency with the absolute, physics-bound security of Quantum Key Distribution (QKD) and Physical Random Oracles (PROs), such as Physical Unclonable Functions (PUFs). This volume details these hybrid primitives, addressing structural vulnerabilities in standard PQC and QKD. Key architectural syntheses include the Lattice PUF, which provably binds ML-modeling resistance to the LWE problem hardness using PAC theory, and Quantum-Locked Physical Mamun, SM (2026) …………………………………….1 Theoretical and Physical Boundaries of Lattice-Based Post-Quantum Cryptography: An Anatomical Critique of Hybrid Info-Theoretic and Computational Primitives (Vol-II) K S C Primitives (HLPUF, HEPUF), which utilize conjugate coding and entanglement to provide authentication guarantees independent of algorithmic hardness.

Abstract: This study develops a scope of analytical framework for integrating quantum cryptography, quantum communications, post-quantum cryptography and nano-enabled hardware security into global cybersecurity architectures for DefenceTech, FinTech and SpaceTech. The research problem is framed by the convergence of three pressures: the long-lived confidentiality exposure created by harvest-now-decrypt-later attacks, the rapid standardization of post-quantum algorithms, and the need for hardware-rooted trust in physically exposed devices, satellites, edge nodes and payment infrastructures. The paper synthesizes quantum key distribution, quantum-network standardization, crypto-agile migration, physical unclonable functions and sectoral governance into a single evaluation model. It uses a public-source calibrated realistic dataset of 18 high-value scenarios across defence, finance and space systems. The dataset is not represented as confidential operational telemetry; rather, it is explicitly constructed from publicly available threat, standards and engineering indicators to support transparent modelling. The methodology combines literature review, structured scenario analysis, weighted risk scoring, residual-risk modelling, expected annual loss estimation and feasibility-sensitive control selection. Mathematical equations are used to express QKD channel attenuation, secret-key-rate intuition, cryptographic migration risk, expected loss and multi-criteria optimization. Results indicate that hybrid PQC adoption produces the broadest near-term risk reduction, QKD offers the strongest value where long-lived secrets and controlled optical paths exist, and nano-enabled roots of trust are especially relevant to contested devices and supply chains. The study proposes a staged global framework in which crypto-agility, hybrid PQC, QKD network governance and nano-PUF attestation are treated as complementary layers rather than competing security paradigms. The conclusion identifies future work in real operational benchmarking, satellite-QKD testbeds, standards-aligned implementation assurance and machine-verifiable security reasoning.
