The Migration Puzzle
Organizations face a puzzle:
- Threat: Quantum computers will break current encryption (5-15 years)
- Solution: Post-quantum cryptography (PQC) is ready
- Challenge: Migrating without breaking existing systems
The puzzle: How do you transition trillions of encrypted communications to quantum-safe algorithms without massive disruption?
Why Migration is Hard
Technical Challenges
- Compatibility: New algorithms use different key sizes, signatures
- Performance: PQC is sometimes slower than classical crypto
- Integration: Hybrid approaches (classical + PQC) add complexity
- Verification: How do you know the migration worked?
Organizational Challenges
- Scope: Affects every system using encryption
- Timeline: Must complete before quantum threat materializes
- Cost: Significant investment required
- Risk: Mistakes could expose data
Knowledge Challenges
- Expertise: Few people understand PQC implementation
- Standards: Multiple algorithms, complex to choose
- Tools: Limited mature migration frameworks
- Training: Workforce needs education
PQCHelp Framework
PQCHelp is emerging framework/tool helping organizations navigate PQC migration:
Assessment Phase
- Inventory: Catalog all cryptographic systems
- Prioritize: Which systems are most critical?
- Risk Analyze: What’s the quantum threat to each system?
- Timeline: By when must each system be migrated?
Planning Phase
- Algorithm Selection: Which PQC algorithms for each use case?
- Hybrid Strategy: How to combine classical + PQC?
- Testing Plan: How to validate migration?
- Resource Planning: What budget/people/time needed?
Implementation Phase
- Pilot: Start with non-critical systems
- Gradual Rollout: Expand to broader deployments
- Continuous Validation: Verify security throughout
- Monitoring: Detect problems quickly
Verification Phase
- Correctness: Did migration work as planned?
- Performance: Is performance acceptable?
- Security: Are systems actually quantum-safe?
- Compliance: Meet regulatory requirements?
Real Example: Financial Institution
Scenario
A bank with:
- 1,000+ systems using RSA encryption
- $500M in annual digital transactions
- Regulatory requirements for quantum safety
PQCHelp Approach
Assessment (3 months):
- Inventory: 1,200 cryptographic implementations found
- Prioritize: 100 critical systems identified
- Risk: High-value transactions top priority
- Timeline: 3-5 years to complete migration
Planning (2 months):
- Algorithm: ML-KEM for key exchange, ML-DSA for signatures
- Hybrid: Classical RSA + ML-KEM in parallel (2-3 years)
- Testing: 20% of systems in pilot first
- Resources: $50M budget, 50 engineers, 2-year project
Implementation (24 months):
- Pilot: 200 systems successfully migrated
- Rollout: 1,000 systems updated
- Validation: Security audit by third parties
- Monitoring: Real-time anomaly detection
Verification (3 months):
- Audit: All systems post-migration
- Performance: Within acceptable parameters
- Security: Cryptographic validation
- Compliance: Regulatory sign-off
Result: Quantum-safe financial infrastructure.

Common Mistakes to Avoid
1. “Set and Forget”
Mistake: Migrate once, assume it’s done forever. Reality: Quantum threat evolves. Continuous monitoring needed.
2. “Wait for Perfect”
Mistake: Delay migration until algorithms are perfect. Reality: NIST standards are good enough. Act now.
3. “Pure PQC Immediately”
Mistake: Replace all classical crypto with PQC overnight. Reality: Hybrid approach provides safety and flexibility.
4. Ignore Legacy Systems
Mistake: Only migrate new systems, ignore old ones. Reality: Legacy systems often hold most critical data.
5. No Verification
Mistake: Assume migration worked without testing. Reality: Verify security through cryptographic validation.
