Post-Quantum Readiness: Insights from ISACA Doha Chapter at Google Cloud Qatar

Modern digital infrastructure relies heavily on public-key cryptography to protect communications, authenticate identities, and establish secure connections.

Future cryptographically relevant quantum computers could undermine widely deployed public-key algorithms, including RSA and elliptic-curve cryptography.

One significant concern is the Harvest Now, Decrypt Later threat, in which encrypted information collected today could potentially be decrypted using sufficiently advanced quantum computers in the future.

For organizations managing sensitive information with long confidentiality requirements, preparing for this transition is increasingly relevant to long-term risk management.

A central consideration is that post-quantum readiness extends beyond replacing cryptographic algorithms.

Organizations need to understand where cryptography is deployed, which systems depend on vulnerable algorithms, and how those dependencies affect future technology transitions.

Effective preparation involves assessing cryptographic exposure, reviewing third-party technology dependencies, establishing migration priorities, and developing crypto-agility—the capability to adapt cryptographic mechanisms as standards and risks evolve.

These considerations are particularly important for organizations managing complex digital infrastructure, long-term data protection requirements, and extensive supplier ecosystems.

The transition toward post-quantum cryptography is already progressing.

In August 2024, the U.S. National Institute of Standards and Technology (NIST) finalized its first three principal post-quantum cryptography standards:

• FIPS 203 – ML-KEMPost-quantum key establishment.
• FIPS 204 – ML-DSAPost-quantum digital signatures.
• FIPS 205 – SLH-DSAStateless hash-based digital signatures.

Google Cloud has also published a post-quantum cryptography roadmap targeting broader readiness across its infrastructure and services by 2029.

These developments reinforce the importance of incorporating cryptographic transition planning into organizational risk assessments and long-term technology strategies.

At Hinology Technology Consulting LLC, we recognize post-quantum readiness as an emerging consideration for digital infrastructure advisory, technology risk management, and organizational resilience.

The transition requires coordination between business leadership, risk management functions, technology providers, and qualified cryptographic specialists.

Organizations can begin preparing by examining cryptographic dependencies, assessing supplier readiness, incorporating future cryptographic requirements into procurement decisions, and developing structured transition plans.

Post-quantum readiness is not simply about adopting new encryption technologies. It is about understanding cryptographic risk, strengthening adaptability, and preparing digital infrastructure for long-term change.
