How Quantum Cybersecurity Changes the Way You Protect Data
Quantum computing is nearing a pivotal point that could revolutionise data protection practices. The development of cryptographically relevant quantum computers (CRQCs) poses significant risks to current encryption methods, making it imperative for organisations to adopt post-quantum cryptography (PQC) to safeguard their data.
Key Points
- The advent of quantum computing threatens to break commonly used encryption algorithms, notably RSA and AES, with unprecedented speed.
- Large-scale adversaries, such as nation-states, are likely stockpiling encrypted data for future decryption.
- Post-quantum cybersecurity is a concern not only for CISOs but for all executive management roles due to the long-term value of sensitive data.
- Current encryption schemes may remain ‘secure’ only because of the time required to break them; CRQCs could breach them in hours.
- NIST has several PQC algorithms but advocates for a defence-in-depth strategy to protect against evolving threats.
- Organisations should prepare now by transitioning to quantum-secure algorithms, which will require comprehensive assessments of IT infrastructure.

This article underscores the urgency for organisations to prepare for the imminent threat posed by quantum computing to data security. It highlights the steps necessary to transition towards quantum-safe cybersecurity measures, which are vital in protecting sensitive information against future breaches. As quantum technology advances, understanding its implications for data protection is critical for maintaining organisational resilience.
