Episode notes
Shor's Algorithm Breaks Today's Asymmetric Crypto
- Shor's algorithm lets a sufficiently strong quantum computer factor RSA and break today's asymmetric crypto.
- That capability would make much of the internet's current PKI and key exchange insecure against future attackers.
Timelines Vary But Regulators Act Now
- There's no consensus on when a cryptographically relevant quantum computer (CRQC) will arrive, estimates range from a few years to decades.
- Governments and standards bodies treat the threat as imminent and are pushing timelines for migration anyway.
Adopt Hybrid Key Exchange For Safer Migration
- Use hybrid key exchange (classical + PQC) during migration to mitigate algorithm or library weaknesses.
- Keep the classical algorithm alongside a post-quantum algorithm until PQC algorithms have sufficient real-world vetting.
