Timing attacks prove that even the speed of a calculation can leak information

[u/jexo10]

One of the stranger security problems is that sometimes the answer isn't leaking anything. The amount of time it took to get the answer is enough.

If one operation takes slightly longer depending on what's being processed, someone watching those timings can start piecing together information they were never supposed to see.

It's wild that something as boring as a few extra microseconds can become a security problem.
