Cache Timing Attack

Definitions

1. A side-channel attack that infers sensitive information by measuring timing differences caused by CPU cache behavior during secret-dependent operations. It is especially relevant in cryptographic implementations and shared-compute environments.

   In plain English: An attack that learns secrets by measuring tiny timing differences caused by CPU cache behavior.

   Example: "The researchers demonstrated a cache timing attack that recovered key-dependent information from the shared host."
