Duration: 2+ months



In our C++ teams in Leuven (BE) and Munich (DE) we work on our LLVM-based solution, iXGuard. By applying code transformations, code injection, binary instrumentation, code analysis, and more, this product focuses on hardening iOS applications against reverse engineering, both static analysis and dynamic tampering.



Mixed Boolean Arithmetic (MBA) is a method to transform simple arithmetic operations into equivalent but much harder to understand expressions. Out of all the possible methods to generate them, mathematical approaches shine for their simplicity, reliability and fast execution time.

This internship is an opportunity to dive deep into the world of arithmetic obfuscation, and grants an opportunity to explore, if and how, we can generate MBA expressions in a fast and efficient manner.



  • Interest in research and publications
  • Some mathematical background
  • C++ experience
