SUMMARY:ReConnaissance: Correctly Tracking Multiple Secrets using Reveal/C
 onceal Paradigms
DESCRIPTION:Amund Bergland Kvalsvik and Magnus Sjalander (Norwegian Univer
 sity of Science and Technology)\n\nSecure speculation schemes are critical
  for defeating speculative side-channel attacks, but often incur notable p
 erformance penalties, encouraging research into optimization strategies. O
 ne such optimization strategy, ReCon, improves performance by exploiting p
 revious non-speculative data leakage to remove protections for already lea
 ked data. However, we find that ReCon can leak secrets when an instruction
  depends on multiple sources of potentially secret data. We show how inter
 actions between Speculative Taint Tracking (STT) and ReCon results in ReCo
 n undermining STT's security guarantees. We address this oversight through
  a low-impact multi-source tracking mechanism that we call ReConnaissance.
  Together with a detailed microarchitecture, we show that, on average, ReC
 onnaissance only lowers the overhead-reduction of ReCon from 23.5% to 18.3
 % on SPEC2017.\n\nTopics: Quantum\n\nTrack: DES6. Quantum Computing, Syste
