A Side channel attack methodology applied to Code-Based Post Quantum Cryptography

The present work proposes a Side Channel Attack that targets the multiplier of a code-based Post Quantum Cryptography primitive. The Secret Key has been recovered with the Correlation Power Analysis obtained with the use of a methodology that simulates the power consumption profile of a design and then validates the method with the real device. The methodology is proposed as a useful tool to study weaknesses of designs during their design phase.
