Right now, your business’s data is like a vault secured with a complex, digital lock. But what if a new technology was being built that could open that lock with a simple click? This isn’t science fiction—it’s the reality of a future threat posed by quantum computers, and the Australian Signals Directorate (ASD) is urging businesses to start preparing.
The “Unbreakable” Lock is Facing a New Key
Most of today’s online security, from banking to customer databases, is protected by complex encryption algorithms. These are so difficult for current computers to break that they’re considered “unbreakable.”
However, a new kind of machine, the Cryptographically Relevant Quantum Computer (CRQC), is on the horizon. This supercomputer will be so powerful that it can easily solve the math problems that make our current encryption secure.
For your business, this means that even if you’re using the best security today, your data could be vulnerable tomorrow. The most significant risk comes from a tactic called “Harvest Now, Decrypt Later”. Attackers are already collecting encrypted data and storing it, waiting for the day they can use a CRQC to unlock it.
The Solution: Building a Quantum-Proof Vault
The good news is that we don’t have to be “sitting ducks.” The cybersecurity community is already developing new, stronger locks. This field, called Post-Quantum Cryptography (PQC), uses algorithms designed to withstand attacks from both current computers and future quantum computers.
The ASD, in line with global standards from organizations like the U.S. National Institute of Standards and Technology (NIST), recommends that Australian businesses begin planning their transition to PQC. Think of it like a scheduled upgrade for your digital security systems. The ASD’s own Information Security Manual (ISM) now advises that organisations stop using older, vulnerable methods by the end of 2030.
A Practical Roadmap: From Awareness to Action
The ACSC’s guide Planning for Post-Quantum Cryptography breaks the journey into clear phases you can start today. (Full guide here)
| Phase | What It Means | Target Date |
|---|---|---|
| Locate | Identify where you use vulnerable encryption (websites, cloud backups, VPNs, email). | Now–2026 |
| Assess | Decide which systems hold sensitive or long-term data (customer info, financial records). | By 2026 |
| Triage | Prioritise what to protect first—critical data and hard-to-update systems. | 2027–2028 |
| Implement | Upgrade to ASD-approved post-quantum algorithms. | Begin by 2028 |
| Communicate & Educate | Inform staff, vendors, and customers about the transition. | Ongoing |
Why Act Early?
- Firstly, smooth transition: Upgrading security takes time and testing.
- Secondly, uncertain timeline: We don’t know exactly when quantum computers will be powerful enough.
- Thirdly, long-term protection: Data you store today could still be valuable a decade from now.
Quick Checklist for Busy Business Owners
- Make a list of all systems that store sensitive data.
- Ask your IT provider or cloud vendors about their post-quantum plans.
- Budget for upgrades and staff training over the next few years.
- Stay updated with ACSC/ASD guidance.
