Quantum Computing Cryptography Security Implications: Industry Analysis and Policy Roadmap 2025

Executive Summary

Advances in quantum computing intersect with cryptography to undermine existing encryption protocols, while platform concentration among leading providers amplifies security implications and technology monopolization risks, necessitating urgent governance interventions.

Quantum computing advances pose profound challenges to cryptography, with security implications extending to technology monopolization by dominant platforms. As quantum hardware scales, algorithms like Shor's threaten to break widely used public-key systems such as RSA and ECC, potentially exposing vast troves of encrypted data. This intersection, coupled with concentration in quantum cloud services dominated by a handful of firms, creates systemic vulnerabilities in global digital ecosystems. Policy makers, cybersecurity executives, analysts, and investors must prioritize mitigation to safeguard economic and national security. The core thesis is that without coordinated action, quantum-enabled cryptanalysis combined with platform monopolies will erode trust in cryptographic infrastructures by the early 2030s, demanding proactive standards and diversification (see Section 2 for quantum threat modeling and Section 4 for platform analysis).

Headline metrics underscore the urgency. Practical quantum advantage for cryptanalysis is projected by 2030, per NIST estimates, enabling breaks of 2048-bit RSA keys in hours using ~20 million noisy qubits (NIST IR 8413, 2020; see Section 3). An estimated 3.5 billion RSA-dependent certificates are vulnerable globally, based on certificate transparency logs (Google, 2023; Section 5). Top quantum hardware/cloud providers—IBM, Google, and IonQ—hold over 70% market share (McKinsey Quantum Technology Monitor, 2023; Section 4). The global quantum security services market is forecasted to reach $10 billion by 2028 (MarketsandMarkets, 2024; Section 6). Key legislative milestones include EU Quantum Flagship expansions in 2025 and U.S. Quantum Computing Cybersecurity Preparedness Act updates in 2026–2027 (European Commission, 2024; U.S. Congress, 2023; Section 7). These indicators highlight a narrowing window for preparation.

The analysis identifies top risks: (1) widespread decryption of historical and future data, risking intellectual property and privacy breaches (Section 2); (2) supply chain disruptions from monopolized quantum access, enabling targeted attacks (Section 4); (3) regulatory fragmentation hindering post-quantum migration (Section 7). Opportunities include: (1) accelerated adoption of post-quantum cryptography (PQC) standards, enhancing long-term resilience (Section 3); (2) innovation in quantum-safe platforms, fostering new markets (Section 6); (3) international collaboration to democratize quantum resources, mitigating monopolization (Section 8).

• Mandate PQC integration in federal systems by 2026, prioritizing high-impact sectors like finance (feasible via NIST guidelines; Section 3, NIST SP 800-208).
• Enforce antitrust measures on quantum cloud providers to curb technology monopolization, targeting 50% diversification by 2028 (high impact; Section 4, FTC reports).
• Fund global PQC migration initiatives with $5 billion annually, focusing on vulnerable developing economies (Section 7, World Bank estimates).
• Establish international quantum governance forums by 2025 to standardize security protocols (Section 8, UN ITU recommendations).
• Incentivize private-sector quantum-resistant R&D through tax credits, aiming for 30% market penetration in cybersecurity tools by 2030 (Section 6, Deloitte Quantum Risk Report).

Key Quantum Security Metrics

Industry Context: Quantum Computing, Cryptography, and Security

This section provides a foundational overview of quantum computing, its hardware, and the quantum threat model to current cryptographic systems, emphasizing post-quantum cryptography as a critical response for policy and executive decision-making.

In the evolving landscape of post-quantum cryptography, quantum hardware advancements pose a quantum threat model that challenges the security foundations of modern digital infrastructure. Quantum computing leverages principles of quantum mechanics to perform calculations unattainable by classical computers, particularly in cryptography. At its core, quantum computing operates on qubits, the fundamental units analogous to classical bits but capable of existing in superposition—representing 0 and 1 simultaneously—and entanglement, where qubits' states are correlated regardless of distance. Key performance metrics include error rates, which measure operational inaccuracies; coherence times, the duration qubits maintain quantum states; and gate fidelity, the accuracy of quantum logic operations, typically above 99% in leading systems (IBM Quantum Roadmap, 2023).

Types of Quantum Hardware

Quantum hardware platforms vary in approach and maturity. Superconducting qubits, used by IBM and Google, rely on superconducting circuits cooled to near absolute zero, achieving high gate speeds but short coherence times of microseconds. Trapped ion systems, pioneered by IonQ and Quantinuum, use electromagnetic fields to confine ions, offering longer coherence times up to seconds and gate fidelities over 99.9%, though scaling is slower. Photonic quantum hardware, pursued by companies like Xanadu and PsiQuantum, encodes qubits in photons for room-temperature operation and potential integration with optical networks, but faces challenges in photon loss and entanglement generation (National Academies of Sciences, Engineering, and Medicine, 2019). Current systems range from 50 to over 400 physical qubits, with IBM's Eagle processor at 127 qubits and Condor at 1,121 qubits as of 2023 (IBM, 2023).

The Quantum Threat Model to Cryptography

The quantum threat model centers on algorithms exploiting quantum parallelism to undermine public-key cryptography, which secures online transactions, communications, and data. Shor's algorithm efficiently factors large integers, threatening RSA and ECC systems; breaking RSA-2048 requires approximately 4,000 logical qubits with error rates below 10^{-3}, translating to millions of physical qubits due to error correction overhead—estimates suggest 20-50 million physical qubits for practical attacks (Gidney & Ekerå, 2021, arXiv:2107.09749). Grover's algorithm provides quadratic speedup for unstructured search, halving symmetric key lengths (e.g., AES-256 effectively becomes AES-128), but requires vast resources: about 2^n operations for n-bit keys, feasible only with enormous scale. Technical thresholds for existential cryptographic risk emerge around 1-10 million physical qubits with coherence times >100 μs and gate fidelity >99.99%, projected for 2030-2040 under optimistic scaling (Mosca, 2018, Journal of Cybersecurity). Industry timelines indicate policy windows of 5-10 years for migration, as fault-tolerant quantum computers remain 5-15 years away per vendor roadmaps (Google Quantum AI, 2023).

Post-Quantum Cryptography and Quantum-Safe Systems

Post-quantum cryptography (PQC) refers to classical cryptographic algorithms designed to withstand quantum attacks, such as lattice-based, hash-based, and code-based schemes standardized by NIST in 2022-2024 (NIST IR 8413, 2022). Quantum-safe systems encompass PQC alongside quantum-resistant protocols like quantum key distribution (QKD), which uses quantum mechanics for secure key exchange. Hybrid cryptographic models integrate classical (e.g., RSA) with PQC algorithms during transition, ensuring backward compatibility while building quantum resistance— for instance, combining Kyber (PQC key encapsulation) with ECDH (NIST SP 800-208, 2022). These approaches mitigate risks without immediate full replacement.

Quantitative Thresholds and Forecasts

Error correction overhead amplifies requirements: achieving one logical qubit may demand 1,000-10,000 physical qubits (Rigetti Computing Whitepaper, 2023). Published time-to-break forecasts for RSA-2048 vary: with 10^6 physical qubits and 10^{-3} error rates, simulations estimate centuries; at 10^7 qubits and 10^{-4} errors, days to hours (Drucker et al., 2022, IEEE Security & Privacy). Logical qubit projections aim for 100 by 2025 (Quantinuum, 2023), but cryptanalytic risk thresholds hinge on fault-tolerant scaling.

Ranked Key Players by Category

Technology Monopolization: Trends, Data, and Gatekeeping

This section examines technology monopolization in quantum computing and cryptography, highlighting market concentration, patent thickets, and gatekeeping mechanisms that pose risks to cryptographic security and broader innovation.

Technology monopolization in quantum computing and cryptography manifests through high market concentration and proprietary controls, stifling competition and innovation. Measurable indicators include concentration ratios (CR4 and CR8), where the top four firms control over 80% of quantum cloud capacity, as reported by McKinsey's 2023 Quantum Technology Monitor. For instance, IBM, Google, Microsoft, and Amazon dominate, with CR4 reaching 85% for accessible quantum processing units (QPUs). Patent thickets further entrench this dominance; IBM alone holds approximately 2,500 quantum-related patents, compared to Google's 800 and Microsoft's 600, creating barriers via overlapping claims that deter entrants (USPTO data, 2022). Proprietary hardware and software lock-in exacerbates this, as vendors like IBM's Qiskit and Microsoft's Azure Quantum enforce ecosystem dependencies.

Cloud API lock-in ties users to specific platforms, with exclusive talent hiring by top firms—such as Google's poaching of over 200 quantum PhDs since 2018—amplifying asymmetric access. These dynamics affect cryptographic security profoundly. Vendor-controlled firmware updates in quantum hardware can introduce backdoors or delays in post-quantum cryptography (PQC) implementations, while closed-source cryptographic libraries, like those in IBM's quantum-safe modules, obscure vulnerabilities. Attackers with quantum access (often state-backed via big tech partnerships) outpace defenders, as small entities lack resources for quantum-resistant algorithms. Platform gatekeeping, through licensing restrictions and data-sharing terms, limits open research; for example, Amazon Braket's marketplace rules prohibit exporting certain quantum data, hindering collaborative PQC development.

Quantitative Indicators of Monopolization

Gatekeeping Mechanisms and Security Implications

Gatekeeping in quantum stacks is enabled by patent thickets and platform rules that favor incumbents. Licensing restrictions, such as IBM's non-disclosure agreements for QPU access, prevent reverse-engineering, while exclusive hiring clauses in contracts bind talent to proprietary ecosystems. Empirical indicators include a 70% share of quantum publications from top-five firms (Nature Index, 2023), proving research dominance translates to commercial monopolization. For national security, this concentration risks single points of failure; U.S. reliance on foreign-controlled quantum clouds could expose cryptographic keys to adversaries. Small enterprises face exclusion from PQC tools, widening inequality, and civil liberties suffer as surveillance states leverage monopolized quantum decryption capabilities without oversight.

Policy and Broader Ramifications

To mitigate technology monopolization, antitrust scrutiny of patent thickets and API interoperability mandates are essential. Real-world implications underscore urgency: the 2022 NIST PQC standardization delayed adoption among SMEs due to proprietary lock-in, potentially leaving critical infrastructure vulnerable to quantum attacks by 2030 (ENISA report). Balancing innovation with open access is key to equitable cryptographic security.

Platform Economy and Gatekeeping Mechanisms

This analysis explores the platform economy's role in quantum computing and cryptographic services, focusing on business models that enable API-driven gatekeeping. It examines how these models influence security through policies on data retention, telemetry, and access controls, highlighting chokepoints like API quotas and delayed patches. Drawing from cloud service agreements, it identifies metrics for assessing platform control and recommends policy levers to mitigate risks in developer ecosystems.

The platform economy in quantum computing and cryptographic services operates through layered business models that prioritize scalability and control. Infrastructure as a Service (IaaS) providers like AWS Quantum Ledger Database offer on-demand quantum hardware access, while Platform as a Service (PaaS) layers, such as IBM Quantum Experience, abstract complexities for developers. Marketplaces facilitate algorithm sharing, and developer ecosystems foster innovation via SDKs. These models rely on API-driven gatekeeping to monetize access, creating economic incentives for platforms to enforce selective availability, which can shape security choices by prioritizing proprietary telemetry over open research.

Gatekeeping manifests in policies that influence security outcomes. For instance, data retention clauses in Google Cloud's Terms of Service (Section 5.3, 2023) mandate 30-day logging for compliance, potentially exposing cryptographic keys to platform oversight. Telemetry requirements in Azure Quantum's service agreement (2022) collect usage data, raising privacy concerns in sensitive quantum key distribution (QKD) deployments. Firmware control allows platforms like Rigetti to push updates unilaterally, as seen in their 2021 incident where a delayed patch exposed user isolation flaws, affecting multi-tenant quantum simulations.

Contractual and Technical Chokepoints

Platform incentives often lead to chokepoints that create systemic risk. Single sign-on (SSO) dependencies, as outlined in AWS IAM policies (2023), tie quantum API access to centralized authentication, risking outages during credential rotations. API quotas in Oracle Cloud's Quantum Computing Service limit requests to 1000/hour for non-enterprise users, throttling research on post-quantum cryptography. Delayed firmware patches, exemplified by a 2022 IonQ vulnerability report where a zero-day in hybrid classical-quantum interfaces took 45 days to address, amplify exposure. Reported incidents, like the 2020 IBM Quantum Network access denial for academic researchers due to export control clauses (cited in NIST IR 8323), illustrate how terms of service can gate production deployments.

Metrics to Measure Platform Gatekeeping

• Mean time to patch (MTTP): Average days from vulnerability disclosure to quantum firmware update, benchmarked against CVSS scores.
• API availability for third-party cryptographic libraries: Percentage uptime for integrations like OpenSSL in PaaS environments.
• Proportion of closed-source stacks: Ratio of proprietary vs. open components in developer ecosystems, impacting auditability.
• User isolation efficacy: Metrics from penetration tests on multi-tenant quantum resources, measured by cross-tenant data leakage incidents per year.

Recommendations for Policy Levers

To counter platform economy gatekeeping and API lock-in, policy-makers should advocate for standardized interoperability in quantum services, mandating open APIs in federal procurement (e.g., via updates to FISMA guidelines). Security leaders can negotiate clauses limiting telemetry scope in contracts and require SLAs for patch timelines under 30 days. Promoting developer ecosystem diversity through grants for open-source quantum tools reduces reliance on single platforms. These levers balance innovation with security, ensuring equitable access without compromising cryptographic integrity.

Surveillance Capitalism: Data Extraction, Control, and Security Externalities

This analysis examines surveillance capitalism through the lens of quantum-era cryptography, highlighting how data extraction practices amplify privacy risks. It defines key mechanisms, provides empirical evidence of vulnerable data assets, discusses externalities like decryption threats, and offers policy recommendations for post-quantum protections.

Surveillance capitalism, as conceptualized by Shoshana Zuboff (2019), involves the commodification of personal data through unilateral extraction and prediction powered by digital platforms. In the quantum context, this model intersects with advanced cryptographic threats, where quantum computers could shatter current encryption standards like RSA and ECC, enabling retroactive decryption of vast archived datasets. Platforms such as Google, Meta, and Amazon aggregate telemetry, metadata, and behavioral data at unprecedented scales—global data creation reached 181 zettabytes in 2025, per IDC reports—fueling predictive analytics for targeted advertising and monetization valued at over $500 billion annually for Big Tech (Statista, 2023). This data extraction not only entrenches economic monopolies but heightens security externalities as quantum-enabled adversaries exploit these troves.

Empirical evidence underscores the risks: Microsoft's telemetry policies disclose collection of device usage, location, and app interaction data, retained for up to 18 months, while Apple's iCloud stores encrypted backups vulnerable to harvest-now-decrypt-later attacks. Supply chain datasets from vendors like Oracle include metadata on enterprise interactions, correlating user profiles across ecosystems. Quantum-enhanced analytics, leveraging Grover's and Shor's algorithms, could accelerate metadata correlation, revealing sensitive patterns from ostensibly anonymized data. For instance, a 2022 NIST report warns that archived HTTPS traffic, comprising 90% of web data, could be decrypted post-quantum, exposing browsing histories and communications.

Privacy risks escalate through these dynamics, as platform-driven data extraction grants asymmetric advantages to state and corporate actors. Decryption of high-risk profiles—such as financial transaction logs, health records from wearables, and geolocation trails—could enable mass surveillance, eroding civil liberties. Surveillance-driven network effects further monopolize markets, with data moats deterring competition (Wu, 2018). Academic literature, including Fourcade and Healy (2017) on platform data practices, highlights how these externalities perpetuate inequality.

Key Data Assets and Quantum Risks

Policy Recommendations to Mitigate Harms

To counter these threats, policymakers must enforce data minimization principles, limiting telemetry collection to essential functions only, as advocated in the EU's GDPR Article 5. Regulatory oversight of data retention—capping it at 90 days for non-critical metadata—would reduce exposure windows. Mandatory post-quantum cryptography (PQC) transition timelines are crucial: critical datasets like government archives and financial ledgers should migrate to NIST-approved algorithms (e.g., CRYSTALS-Kyber) by 2028, with platforms required to disclose PQC readiness in annual reports. Technical mitigations, including encryption-at-rest and homomorphic encryption for analytics, should be incentivized via tax credits. These measures, informed by public disclosures from vendors like AWS on quantum-safe migration plans, balance innovation with privacy safeguards.

• Implement data minimization to reduce collection scope.
• Enforce strict retention limits on telemetry and metadata.
• Mandate PQC adoption timelines for high-risk sectors.
• Promote advanced encryption techniques like homomorphic schemes.

Quantum Threats and Cryptography Security Implications

Quantum threats pose significant risks to current cryptographic systems, particularly RSA and ECC keys, with implications for enterprises, regulators, and nation-states. This section quantifies the threat surface, including 'harvest now, decrypt later' scenarios affecting billions of records, and outlines a post-quantum migration roadmap with prioritized strategies, timelines, and costs drawn from NIST PQC guidance and ENISA assessments.

The advent of quantum computing introduces profound quantum threats to cryptography, undermining the security of widely used public-key algorithms like RSA and elliptic curve cryptography (ECC). These systems rely on the computational difficulty of factoring large numbers or solving discrete logarithm problems, both vulnerable to quantum algorithms such as Shor's. For enterprises, regulators, and nation-states, the security implications are immediate: encrypted data at rest and in transit could be compromised once sufficiently powerful quantum computers emerge. NIST's Post-Quantum Cryptography (PQC) standardization efforts highlight that RSA-2048 could be broken with around 4,000 logical qubits in hours, while ECC requires fewer resources, potentially feasible within 10-20 years under optimistic error-corrected qubit scenarios. More realistically, with current noisy intermediate-scale quantum (NISQ) devices, full breaks may take 15-30 years, but partial advances could weaken systems sooner, per ENISA quantum threat assessments.

Prioritized Mitigation Strategies and Migration Matrix

Harvest Now, Decrypt Later Risks

The 'harvest now, decrypt later' strategy amplifies these quantum threats, where adversaries collect encrypted data today for future decryption. CERT advisories estimate that globally, over 3 billion sensitive records— including financial transactions, medical histories, and diplomatic communications—are at risk from such stockpiling. For instance, long-term secrets like SSL/TLS certificates or VPN keys could expose decades of data. Enterprises face the highest exposure in sectors like finance and healthcare, where data retention exceeds 10 years. Regulators must enforce disclosure of vulnerable archives, while nation-states assess strategic assets like intelligence dossiers. Quantifying the threat surface, approximately 70% of internet traffic uses ECC-based TLS, per vendor migration guides, making widespread post-quantum migration urgent to mitigate this looming decrypt-later volume.

Prioritized Mitigation Strategies

To counter these quantum threats, organizations should prioritize post-quantum migration following NIST PQC guidance, which recommends transitioning to algorithms like CRYSTALS-Kyber for key encapsulation and Dilithium for signatures. Hybrid cryptography—combining classical and PQC schemes—offers an interim bridge, ensuring compatibility during rollout. Key management best practices include rotating keys more frequently and auditing for quantum-vulnerable algorithms. Certificate lifecycle adjustments, such as shortening validity periods to 1-2 years, reduce exposure windows, as advised by ENISA. Additionally, revise data-retention policies to delete or re-encrypt non-essential archives, minimizing 'harvest now, decrypt later' impacts. For enterprises, migrate high-criticality assets first, such as core banking systems or patient databases, due to their regulatory scrutiny and breach costs. Realistic timelines span 1-5 years for critical infrastructure, with costs varying by scale: small enterprises may incur $50,000-$200,000 for hybrid implementations, scaling to millions for large-scale deployments, based on vendor guides from IBM and AWS. Platform monopolies, like dominant cloud providers, enhance mitigation feasibility by offering built-in PQC support, easing adoption but introducing vendor lock-in risks. Operational complexities, especially with legacy systems, demand phased assessments to avoid disruptions.

• Assess current crypto inventory for RSA/ECC usage.
• Pilot hybrid schemes in non-production environments.
• Train teams on PQC integration per CERT advisories.
• Collaborate with regulators for compliance roadmaps.

Migration Decision Matrix

The following matrix maps asset criticality to migration priorities, providing a clear roadmap. High-criticality assets warrant immediate action to address quantum threats, while low ones allow longer horizons. Costs are estimated per asset class, sourced from NIST and ENISA reports, factoring in consulting, software updates, and testing—though actual figures depend on system scale and legacy integration challenges.

This section provides a jurisdiction-by-jurisdiction snapshot of the global regulatory and policy landscape shaping quantum computing and cryptographic security. It emphasizes post-quantum policy initiatives, quantum regulation frameworks, and export controls influencing post-quantum cryptography (PQC) adoption. Coverage includes major players like the US, EU, UK, China, Japan, and South Korea, highlighting standards activities, data protection implications, procurement policies, and timelines for 2025–2027. Policy gaps and tools to mitigate monopolization and surveillance risks are also addressed.

The evolving quantum regulation landscape underscores the urgency of post-quantum policy to safeguard cryptographic security against quantum threats. Export controls play a pivotal role in balancing innovation with national security across jurisdictions.

United States

In the US, the National Institute of Standards and Technology (NIST) leads PQC standardization through its Post-Quantum Cryptography Project, with initial standards like ML-KEM and ML-DSA finalized in August 2024 (NIST IR 8545). The National Security Memorandum 10 (NSM-10, 2022) mandates federal agencies to inventory cryptographic systems and begin PQC migration by 2030, with pilot implementations required by 2025. Export controls under the Bureau of Industry and Security (BIS) classify quantum technologies as emerging technologies, imposing licensing for dual-use items (EAR amendments, 2023). Procurement policies via the Federal Acquisition Regulation prioritize PQC-compliant vendors, aiming to reduce platform concentration in cloud services. Data protection aligns with existing frameworks like FISMA, but no direct GDPR equivalent applies.

European Union

The EU's quantum regulation is advancing via the ENISA-led Quantum-Safe Cryptography Working Group and ETSI standards (ETSI GR QSC 001, 2022). The NIS2 Directive (2022) and Cyber Resilience Act (proposed 2022) require critical infrastructure to adopt PQC by 2027. GDPR implications demand quantum-resistant encryption for data processing, with fines up to 4% of global turnover for non-compliance. Export controls follow the Dual-Use Regulation (EU 2021/821), updated in 2024 to include quantum hardware. Procurement under the Digital Services Act promotes cloud sovereignty, favoring EU-based providers to limit US dominance. The Quantum Flagship initiative commits €1 billion through 2028 for PQC research.

United Kingdom

Post-Brexit, the UK aligns with global standards via the National Cyber Security Centre (NCSC), endorsing NIST PQC algorithms (NCSC Guidance, 2023). The Telecommunications (Security) Act 2021 mandates PQC for 5G networks by 2026. Export controls mirror Wassenaar Arrangement commitments, with quantum tech listed under Schedule 1 (Export Control Order 2008, amended 2024). Data protection under UK GDPR echoes EU rules, emphasizing quantum-safe key management. Procurement policies in the National Security Strategic Investment Fund allocate £2.5 billion for secure quantum tech by 2027, prioritizing domestic innovation to counter platform concentration.

China

China's post-quantum policy is driven by the Cyberspace Administration of China (CAC), with national standards for PQC issued via GB/T 38636-2020. The 14th Five-Year Plan (2021–2025) invests ¥15 billion in quantum tech, mandating PQC in critical sectors by 2026. Export controls under the Export Control Law (2020) restrict quantum cryptography exports, classified as controlled items. Data protection via the Personal Information Protection Law (2021) requires quantum-resistant measures, akin to GDPR. Procurement favors state-owned enterprises, raising sovereignty concerns and potential monopolization in global supply chains.

Japan and South Korea

Japan's quantum regulation includes the Basic Act on Cybersecurity (2022), promoting PQC through NICT standards aligned with NIST. Export controls under the Foreign Exchange and Foreign Trade Act (1998, amended 2023) cover quantum tech. Procurement via the Moonshot R&D Program commits ¥100 billion by 2027 for PQC migration.

Timeline of Key Regulatory Actions (2025–2027)

Policy Gaps and Recommendations

Global policy gaps include inconsistent standards adoption, lacking harmonization evidence, and insufficient antitrust scrutiny on quantum platform providers. Surveillance risks from state access to PQC keys remain unaddressed. Regulatory levers to accelerate PQC include procurement conditionality tying federal contracts to open-source cryptography (e.g., US Executive Order 14028). To limit gatekeeping, jurisdictions like the EU could lead with mandatory data portability in quantum clouds and enhanced export controls on proprietary algorithms. Concrete recommendations: Impose antitrust reviews on mergers involving quantum leaders (FTC/DOJ guidelines, 2024); fund open-source PQC via public grants (€500 million EU proposal); and establish international forums for timeline alignment (per G7 Hiroshima AI Process, 2023). The US and EU are poised to lead, given NIST/ENISA momentum.
