One Cryptographic View Across IT and OT.
Bridge the operational divide. Map hidden cryptographic dependencies and coordinate transition roadmaps across standard corporate software and long-lived industrial networks.
Corporate & Software Infrastructure
Standard lifecycle environments. Upgrades, patching, and certificate rotatability are typically automated or managed via standard operations.
Cloud Platforms
SaaS databases, serverless computing, and AWS/Azure/GCP virtual instances relying on public-key exchanges.
Business Applications
Internal payroll, customer relationship platforms, and legacy ERP systems using hardcoded cryptography.
REST APIs
Machine-to-machine integrations and microservice architectures communicating via legacy TLS configurations.
Identity Providers
Active Directory, Okta, and SAML token signing structures dependent on public key encryption.
Enterprise PKI
Corporate root and intermediate certificate authorities managing employee and device identities.
TLS & IPSec
Transport Layer Security and Virtual Private Networks protecting data in transit across corporate locations.
Industrial & Physical Infrastructure
Extended lifecycle environments. Physical access restrictions, safety parameters, and hardware resource constraints make automated updates impossible.
SCADA Systems
Supervisory Control and Data Acquisition architectures managing water, power, and transit controls.
Hardware PLCs
Programmable Logic Controllers with severe physical, processor, and memory constraints.
ICS Systems
Industrial Control Systems relying on hardcoded, immutable trust profiles and older encryption standards.
Device Firmware
Low-level machine instruction sets embedded on field processors that cannot easily run post-quantum maths.
Industrial Gateways
Network translation devices mapping operational assets to corporate routing layers.
Long-Lived Assets
Physical equipment (turbines, switches, machinery) with operational lifespans exceeding 30 years.
Why OT Cryptography Requires Lifecycle and Dependency Awareness
Operational Technology (OT) manages physical actions in real-world assets. Unlike typical corporate software where certificates expire and rotate within days, OT systems are engineered to run undisturbed for decades.
Upgrading operational equipment presents severe engineering constraints:
- Processor Limitations: Legacy field devices contain microprocessors unable to compute larger post-quantum keys (like ML-KEM).
- Immutable Firmware: Many field PLCs and devices rely on firmware images where cryptographic functions are burned directly onto silicon.
- Continuous Operations: Power generation, transport grids, and chemical facilities cannot tolerate the testing or rollout outages common in IT networks.
Therefore, transition requires a dual approach: applying quantum-resistant cryptography to IT networks, while implementing protocol wrapper isolation and lifecycle protection for vulnerable operational assets.
