Quantum Readiness
Preparing cryptographic estates for post-quantum algorithms, and assessing where quantum computing may eventually apply.
How ready this is, and for what
What it is
Understanding Quantum Readiness
Quantum readiness has two distinct parts. The urgent one is cryptographic: sufficiently capable quantum computers would break widely used public-key cryptography, and standards bodies have published post-quantum algorithms in response. The speculative one is quantum computing applied to optimization and simulation problems.
Why it matters
The cryptographic part is a real near-term planning concern because of "harvest now, decrypt later" — data intercepted today can be stored and decrypted once capability exists. For long-lived confidential data, migration planning is a present-day decision, not a future one.
Problems it addresses
- “We do not know where public-key cryptography is used across our estate.”
- “Our data has a confidentiality lifetime measured in decades.”
- “Cryptographic algorithms are hard-coded across our applications.”
Capabilities
Cryptographic inventory
Discovering where and how cryptography is used across the estate.
Crypto-agility assessment
Establishing how hard algorithm replacement would actually be.
Post-quantum migration planning
A prioritized, standards-aligned transition roadmap.
Education and use-case assessment
A realistic view of where quantum computing may and may not apply.
Use cases
Cryptographic inventory
The prerequisite for any migration planning.
Long-lived data protection
Prioritizing data whose confidentiality must outlast current cryptography.
Crypto-agility engineering
Making algorithm replacement a configuration change rather than a rebuild.
Before you commit
Prerequisites, governance and risks
The questions that determine whether this will work in your environment, rather than in a demonstration.
What has to be true first
- An asset and data inventory
- Understanding of data confidentiality lifetimes
- Vendor roadmap engagement
Governance
This is a planning and inventory activity, not a technology deployment. The deliverable is knowing where cryptography lives and how quickly it could be changed. Resilience Solutions publishes a point of view on quantum readiness; it does not claim quantum computing delivery capability.
Risks
- Over-investing in a speculative timeline
- Under-investing in crypto-agility, which is valuable regardless of quantum timelines
- Vendor claims outpacing demonstrated capability
