Google warns quantum computers could hack encrypted systems by 2029

TL;DR

  • Google warns quantum computer hackers could break existing encryption systems by 2029.
  • This poses a significant threat to current cryptographic standards and online security.
  • Google recommends prioritizing migration to post-quantum cryptography for authentication services.
  • Quantum computers are a nascent technology with significant development hurdles, including qubit stability.
  • Timelines for cryptographically relevant quantum computers vary, but the threat is close enough for governments to prepare.
  • Intelligence communities have been considering this threat for over a decade.
  • The UK's cybersecurity agency suggested guarding systems against quantum hackers by 2035.
  • "Store now, decrypt later" attacks, predicated on future quantum decryption availability, may already be in use.
