Quantum Computing an

Introduction

Quantum computing promises breakthroughs in science and technology — but it also threatens to break much of the encryption we rely on today.

ASD and ACSC are encouraging organisations to start thinking about quantum readiness. While the quantum future isn’t here yet, businesses that prepare early will be safer and more competitive.

Why Quantum Matters for Cyber Security

•    Current public key cryptography (RSA, ECC) could be broken by future quantum computers
•    Sensitive data stolen today could be decrypted years later (“harvest now, decrypt later”)
•    Governments and large enterprises are already planning their transition

What Businesses Can Do Now

1.    Understand your cryptography: Know what encryption your systems use
2.    Classify your data: Identify information that must stay secure for 10+ years
3.    Stay informed: Follow ASD, ACSC, and NIST post-quantum cryptography standards
4.    Adopt crypto agility: Choose systems that can be updated to new algorithms easily
