A Practitioner’s Guide to Post-Quantum Cryptography
Release Date: 11/10/2025
Cryptographically relevant quantum computers are projected to emerge as early as the 2030s. Traditional cryptographic systems like RSA, Diffie-Hellman, and elliptic curve algorithms face obsolescence. This guide from the CSA Quantum-Safe Security Working Group provides a practical roadmap for organizations seeking to assess, plan, and mitigate quantum computing risks.
Building on prior CSA research, these actionable steps are tailored for enterprises that may lack in-house cryptographic expertise. The document explains how to identify vulnerable cryptographic components, assess “store now, decrypt later” threats, and map out mitigation strategies for encryption in transit and at rest.
Readers will gain insights into emerging post-quantum standards (such as NIST FIPS-203, -204, and -205), hybrid key exchange protocols, and experimental post-quantum cryptography (PQC) modules.
Prepare your organization for a post-quantum future while maintaining backward compatibility and resilience during the transition.
Key Takeaways:
- Quantum computing’s impact on today’s cryptographic systems
- How to assess and prioritize data at risk from quantum attacks
- Mitigation options and PQC implementation strategies
- Cloud Controls Matrix principles that apply to quantum-safe governance
