CONFISCA : an SIMD-based CONcurrent FI and SCA countermeasure with switchable performance and security modes

Ehsan Aerabi and Cyril Bresch and David Hély and Athanasios Papadimitriou and Mahdi Fazeli

Abstract

CONFISCA is the first SIMD-based cipher implementation methodology which can concurrently resist against Side Channel Attack (SCA) and Fault Injection (FI). Its promising strength is presented in a PRESENT cipher case study. It has a considerably less performance and memory overhead in comparison to the previous concurrent countermeasures. By having one instance of the cipher, CONFISCA can on-the-fly switch between its two modes of operation: The High-Performance and High-Security. This gives us the flexibility to trade performance/power with security, based on the actual needs.
