Quantum Computing Threatens Encryption, Upending Cybersecurity Defenses for Billions

3 articles · Updated · The Wall Street Journal · Aug 25

Summary

  • Quantum computing is poised to undermine today’s cybersecurity by making it easier to crack the encryption codes that protect digital data.
  • That threat stems from quantum machines’ ability to solve certain complex math problems more efficiently than standard computers, weakening the foundations of current encryption.
  • The risk is broad because those encryption systems underpin everyday data security, leaving governments, companies and consumers exposed as quantum capabilities advance.

Insights

If hackers are already stockpiling your encrypted data today, will tomorrow's quantum computers make your deepest secrets completely public?
Could the massive file sizes of new quantum-proof encryption keys actually crash the legacy networks we rely on daily?
