scene cut

Hertzbleed demonstrated a timing side-channel that can leak secrets from modern CPUs (source). It reinforced that performance features can create security tradeoffs.

  • Side-channel risk persists in modern chips.
  • Performance optimizations can leak data.
  • Mitigation often requires ecosystem coordination.
  • The hardware risk pairs with CPU Branch Prediction Evolution.
