Key Components of the Roadmap
Phase 1: Assessment
Inventory & Discovery
- Identify cryptographic assets
- Catalog vulnerable algorithms
- Map data security requirements
- Assess system dependencies
Phase 2: Planning
Roadmap Development
- Prioritize critical systems
- Develop transition strategy
- Engage with vendors
- Build cryptographic agility
Phase 3: Implementation
Migration & Validation
- Deploy PQC algorithms
- Test & validate security
- Verify interoperability
- Monitor performance
Transition Challenges & Solutions
| Challenge | Impact | Recommended Solution |
|---|---|---|
| Legacy Systems | May not support new algorithms | Prioritize replacement or isolation strategies |
| Interoperability | Systems with different migration timelines | Implement hybrid cryptography approaches during transition |
| Performance Concerns | PQC algorithms may require more resources | Benchmark early, update hardware where needed |
| Supply Chain Issues | Vendor dependencies and support | Engage vendors early, request roadmaps |
