Post-Quantum Cryptography: It’s time to act!

Quantum computers are no longer science fiction—they’re becoming a reality. While they promise breakthroughs in fields like medicine and logistics, they also pose a serious threat to today’s encryption systems. Algorithms like RSA and ECC, which protect our emails, financial data, and digital identities, could be broken by quantum machines. Post-quantum cryptography is our defence. It’s a new generation of encryption algorithms designed to withstand both classical and quantum attacks. These algorithms are built on hard mathematical problems that even quantum computers struggle to solve. The urgency is real: attackers can “harvest now, decrypt later”, meaning data stolen today could be decrypted in the future once quantum capabilities mature. That’s why organisations must start transitioning now—before it’s too late. Post-quantum cryptography isn’t just a technical upgrade. It’s a strategic move to safeguard digital trust in the quantum era.
