Namely, we show that one can build 3-out-of-4 obfuscation combiners where at least three of the four combiners are secure, whereas 2-out-of-3 structural combiners (which combine the obfuscator candidates ...
To reduce overhead, we define detecting combiners, where the combined obfuscator may sometimes produce an error-indication instead of the desired output, indicating that some of the component obfuscators ...
Combiners for Obfuscators Roughly, a combiner for obfuscators is a procedure which uses a set of obfuscators O 1 , O 2 , . . . to turn an input circuit C into an obfuscated one, with the guarantee that ...

This means the expected hash values need to be adjusted in the binary executable, hence combining SC with other protections is limited due to this adjustment step. ...
However, large overheads stemming from the virtualization obfuscation were encountered. ...
CONCLUSIONS We designed, implemented and evaluated an LLVM-based protection that effectively combines virtualization obfuscation (VO) and self-checksumming (SC). ...
