SUMMARY:HyCaMi: High-Level Synthesis for Cache Side Mitigation
DESCRIPTION:Research Manuscript\n\nHeiko Mantel, Joachim Schmidt, Thomas S
 chneider, Maximilian Stillger, Tim Weißmantel, and Hossein Yalame (Technis
 che Universität Darmstadt)\n\nCache side-channels are a major threat to cr
 yptographic implementations, particularly block ciphers. Traditional manua
 l hardening methods transform block ciphers into Boolean circuits, a pract
 ice refined since the late 90s. The only existing automatic approach based
  on Boolean circuits achieves security but suffers from performance issues
 . This paper examines the use of Lookup Tables (LUTs) for automatic harden
 ing of block ciphers against cache side-channel attacks.We present a novel
  method combining LUT-based synthesis with quantitative static analysis in
  our HyCaMi framework. Applied to seven block cipher implementations, HyCa
 Mi shows significant improvement in efficiency, being 9.5× more efficient 
 than previous methods, while effectively protecting against cache side-cha
 nnel attacks. Additionally, for the first time, we explore balancing speed
  with security by adjusting LUT sizes, providing faster performance with s
 lightly reduced leakage guarantees, suitable for scenarios where absolute 
 security and speed must be balanced.\n\nTopic: Security\n\nKeyword: Hardwa
