Modern computing systems rely on multilayered memory hierarchies designed for speed, not secrecy. CPU caches — L1, L2, L3 — exist to accelerate access to frequently used data. But that optimization introduces a blind spot: timing differences. Attackers can observe tiny delays in memory access and extract information that should never be accessible. No…
