POST-QUANTUM CRYPTOGRAPHY · AUSTRALIA

Quantum computing will break today’s public-key encryption. ASD recommends moving by 2030.

Data sent today can be read later. Signatures trusted today can be forged later.

The Australian Signals Directorate (ASD) recommends a refined transition plan by the end of 2026, and a complete move to post-quantum cryptography by 2030. We help you get there.

ASD’S MILESTONES FOR EVERY AUSTRALIAN ORGANISATION

These dates come from ASD’s guide, Planning for post-quantum cryptography ↗. ASD’s Information Security Manual ↗ (ISM) will not approve RSA, Diffie-Hellman or elliptic curve cryptography after 2030.

TODAY

  1. BY END OF 2026

    A refined plan

    A plan that reflects your risk tolerance, dependencies and the value of your data.

  2. BY END OF 2028

    Critical systems started

    Starting with critical systems, long-lived data and anything slow to update.

  3. BY END OF 2030

    Transition complete

    Post-quantum cryptography in place, then monitored from 2031.

WHERE TO START

Three steps to begin.

A credible plan is still possible, if work starts now:

  1. 01Understand your exposure. Find your cryptography, in your systems and your suppliers’ products. Rank it by two measures: how long data must stay secret, and how long each system takes to replace.
  2. 02Stop adding to it. Put ASD’s vendor questions into every tender and renewal, and judge the answers with the PKI Consortium’s PQC Maturity Model. Ask for post-quantum roadmaps in contracts. This can start before step 1.
  3. 03Put a plan in front of your board. Directors are expected to oversee material risks, and this is one. Give them owners, dates and the 2028 milestone, even if the inventory isn’t finished.

HOW WE WORK

Six services, mapped to ASD’s five phases.

Each service covers one or more phases of ASD’s LATICE framework. Engagements are one-off projects; subscriptions keep the result current.

WHY SOUTHERN QUANTUM

The goal isn’t one migration. It’s being able to change again.

New algorithms will be updated, replaced and broken again. We help you build cryptographic agility: knowing where your cryptography is, and being able to change it without rebuilding your systems.
