Quantum Security Simplified for Critical Infrastructure

Protect your operations against future quantum decryption without ripping and replacing field hardware. Neeve brings NIST-standardized post-quantum cryptography to distributed operational technology (OT) through non-disruptive, software updates.

The Post-Quantum Mandate

Three Reasons Post-Quantum Security Cannot Wait for 2030

NSA Mandates for NSS Start Jan 1, 2027. Neeve is Ready Today.

Transitioning critical infrastructure to post-quantum cryptography doesn’t require replacing edge gateways or scheduling disruptive operational downtime. Neeve has built cryptographic agility directly into its Secure Edge and Secure Link architecture:

Federal Standards & Migration Milestones:

  • Jan 1, 2027 (Federal Acquisition Benchmark): CNSA 2.0 requires all new federal and NSS networking acquisitions to support PQC. Critical infrastructure is adopting this same benchmark.
  • 2030 (Network PQC-Only & Deprecation): Networking equipment and code signing must be PQC-only under CNSA 2.0, while NIST IR 8547 formally deprecates legacy RSA and ECC.
  • 2033–2035 (Complete Legacy Disallowance): Full federal deadline across all systems; legacy RSA and ECC are completely disallowed under NIST and NSA standards.

 

The Neeve Execution Roadmap:

  • NOW (Data in Transit): Hybrid X25519 + ML-KEM-1024 encryption across data tunnels, control plane, Keycloak, and update channels, with portal TLS matching the browser’s hybrid ML-KEM. Neutralizes Harvest Now, Decrypt Later today without hardware changes.
  • 2027 (Identity & Authentication): ML-DSA-87 identity deployed via hybrid certificates (dual signatures), keeping existing device credentials valid to prevent operational disruption.

Neeve is your platform to begin post quantum readiness now without rip and replace

A Cryptographically Agile Platform Is Vital

Adversaries are intercepting building management telemetry, energy distribution feeds, and pipeline control data today to exploit when quantum computing matures. Neeve provides an immediate defense layer engineered for high-assurance critical infrastructure.

Frequently Asked Questions

What OT Security Leaders Need to Know

Key architectural, operational, and compliance questions regarding post-quantum cryptography in critical infrastructure.

 

1

What is “Harvest Now, Decrypt Later” (HNDL), and why is OT telemetry at risk today?

Nation-state adversaries are actively intercepting and storing encrypted operational technology (OT) traffic today including SCADA setpoints, building management telemetry, pipeline sensor feeds, and remote engineering credentials. When cryptanalytically relevant quantum computers (CRQCs) emerge, attackers will retroactively decrypt this hoarded data.

NIST’s transition guidance (NIST IR 8547) emphasizes that because of Harvest Now, Decrypt Later (HNDL), organizations must prioritize key encapsulation migration (FIPS 203 / ML-KEM) for data with long-term confidentiality requirements. Because critical infrastructure architectures, firmware keys, and operational data remain sensitive for 10 to 20 years, HNDL is an active risk today, not a distant theoretical concern.

2

Does the NSA CNSA 2.0 mandate apply directly to commercial real estate and industrial operators?

CNSA 2.0 legally binds US National Security Systems (NSS), but it sets the security benchmark for all critical infrastructure. Because building, facility, and industrial field assets operate on 10 to 15-year lifecycles, leading infrastructure operators are aligning procurement with federal milestones to ensure systems deployed today are not obsolete before their operational lifespan ends.

3

What is the official timeline for phasing out legacy RSA and ECC cryptography?

Under NIST IR 8547 (finalized October 2026), legacy RSA and ECC ciphers are formally deprecated after 2030 and fully disallowed after 2035. Under CNSA 2.0 guidance, networking equipment and code signing must transition to PQC-only by 2030, with full system transition completed by 2035.

4

Do we need to reconfigure our existing BMS, SCADA, or PLC devices?

No. Neeve acts as an intelligent, zero-trust SASE overlay. Your field equipment communicates over standard local industrial protocols; Neeve encapsulates all egress and remote access sessions into quantum-safe tunnels automatically.

5

How does Neeve implement post-quantum security without disrupting existing OT devices?

Neeve operates as an intelligent edge overlay. Today, Neeve protects data in transit using hybrid X25519 + ML-KEM-1024 encryption across data tunnels, control planes, and management channels. In 2027, device identity upgrades to ML-DSA-87 using hybrid certificates, allowing existing legacy certificates and local BACnet/Modbus devices to operate seamlessly without hardware rip-and-replace.

6

Why can’t legacy cellular modems and industrial VPN routers simply be upgraded with a firmware patch?

Post-quantum algorithms like ML-KEM and ML-DSA rely on module-lattice mathematics rather than classical RSA or ECC. Their keys and ciphertext packets are substantially larger, often requiring 8x to 15x more data per handshake, demanding significantly more memory and processing power.

Most legacy industrial gateways and VPN concentrators run on low-power microcontrollers with fixed crypto chips limited to RSA/ECC. They physically lack the memory to buffer PQC keys or process hybrid TLS 1.3 handshakes, leading to dropped packets and connection timeouts. In contrast, Neeve Secure Edge nodes are built on modern compute architectures engineered specifically for cryptographic agility and software-delivered protocol updates.

7

Will upgrading to post-quantum encryption degrade edge tunnel performance or latency?

No. ML-KEM (Kyber) is designed for high computational efficiency. Neeve’s edge nodes and SASE cloud orchestrator handle key encapsulation in microseconds without packet fragmentation or perceptible latency on control loops. Key encapsulation only runs during initial handshakes and background session rekeys, while active operational traffic continues at line rate over hardware-accelerated symmetric encryption.

8

What steps should OT cyber-risk managers take today to achieve quantum readiness?

NIST recommends a risk-prioritized migration blueprint for critical infrastructure operators:

  1. Cryptographic Inventory: Identify all external-facing remote access pathways, cellular modems, and VPNs handling OT telemetry and building controls.
  2. Prioritize Data at Risk of HNDL: Focus immediate migration efforts on encrypted pathways carrying telemetry, architectural schemas, and control commands that must remain confidential beyond 2030.
  3. Deploy Cryptographically Agile Edge Architecture: Replace rigid, single-purpose hardware gateways with software-defined edge nodes that can ingest PQC updates over the air without on-site truck rolls.
  4. Establish Dual-Validation Pathways: Ensure remote access and cloud connectivity architectures support side-by-side classical and post-quantum validation, shielding operations from abrupt certificate cutovers.
