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.
