Basic Algorithm

1. A secret byte you want to read is stored at inaccessible memory location priv_mem.
2. The sender triggers an access exception by attempting to access priv_mem.
3. Due to out-of-order execution, the load of secret and its access in step 4 may happen before the exception fires.
4. Calculate an offset into a known array probe by multiplying secret by the width of a cache line.
5. This forces the cache to load probe[offset], caching exactly one chunk of our array.
6. The exception fires, clearing the modified registers, but cached data is not excised.
7. Iterate over all 256 offsets into probe to find out which one loads fast. You've determined the value of secret.
