Explore the impact of quantum computing on cryptography
Quantum computing is set to shake up the world of cryptography and the way we think about data encryption. While much of the buzz surrounding quantum tech focuses on exciting applications like drug discovery, the potential threat it poses to current cryptographic methods can’t be ignored. As research and development progress, it’s wise for data centre managers and security teams to stay informed and ready.
Key Points
- Quantum computers could potentially break many of today’s encryption methods, representing a significant security threat.
- Shor’s algorithm threatens asymmetric cryptography, like RSA, by efficiently factoring large numbers.
- Grover’s algorithm poses risks to symmetric cryptography, enabling faster searches for encryption keys.
- Emerging alternatives for quantum-resistant encryption include lattice-based, code-based, multivariate, and isogeny-based cryptography.
- NIST is actively reviewing potential quantum-resistant algorithms, with four candidates already selected in 2022.
- Organisations are encouraged to begin preparations for a post-quantum world to safeguard against future threats.
