The transition to post-quantum cryptography is a software modernization problem as much as a mathematics problem. The work begins by understanding what your systems depend on.
Why begin before the hardware arrives?
A sufficiently capable future quantum computer could threaten widely used public-key cryptography. NIST recommends moving toward its post-quantum standards before that risk becomes immediate. Migration touches products, protocols, services, and long-lived data. [1]
Post-quantum cryptography runs on conventional computing systems. It is distinct from quantum computing and quantum communication.
Standards create a starting point.
NIST’s first three finalized standards are ML-KEM for key establishment, ML-DSA for digital signatures, and SLH-DSA for an additional signature approach. Selection and implementation need to account for system requirements and applicable guidance. [2]
A practical engineering roadmap.
Map cryptographic dependencies.
Inventory algorithms, certificates, libraries, protocols, vendor services, and the applications that depend on them.
Connect the transition to the mission.
Consider data sensitivity, required confidentiality lifetime, exposure, business continuity, and the difficulty of replacing each dependency.
Design for change.
Establish vendor roadmaps and test environments. Separate cryptographic choices from application logic where practical, so future changes are manageable.
Test the entire workflow.
Evaluate performance, interoperability, operational procedures, and fallback behavior before making production changes.
This roadmap is Omniscient’s engineering perspective. Specific transition requirements depend on the organization, system, and governing policies.
Resilience is an architectural choice.
Documented interfaces, explicit dependencies, and modular implementations help organizations evolve without losing sight of the mission. Our software-first approach connects that discipline to application modernization and systems integration.
