How quantum cybersecurity changes the way you protect data
Quantum computing is advancing rapidly, bringing new cybersecurity challenges as well as opportunities. This article examines the imminent threat posed by cryptographically relevant quantum computers (CRQCs) and discusses the importance of adopting post-quantum cryptography (PQC) to safeguard sensitive information.
Key Points
- CRQCs can potentially break widely used encryption algorithms such as RSA, Diffie-Hellman, and AES.
- Adversaries, especially nation-states, may be hoarding encrypted data with plans to decrypt it once CRQCs become available.
- Organisations with high-value data, including financial institutions, government agencies, and healthcare providers, should be particularly vigilant.
- Post-quantum cybersecurity is not only a CISO concern but also involves CIOs, CEOs, and board members due to the broad impacts on organisational reputation and data security.
- NIST is finalising several PQC algorithms, but organisations must adapt their systems to accommodate new, more complex encryption methods.
Why should I read this?
This article is crucial for understanding how the evolution of quantum computing will transform data protection strategies. As current encryption methods face potential obsolescence, grasping the nuances of quantum cybersecurity can help organisations proactively mitigate risks and secure their critical data against future threats. Staying informed is essential for strategic planning in a rapidly changing technological landscape.
