CONFISCA: An SIMD-Based Concurrent FI and SCA Countermeasure with Switchable Performance and Security Modes

CONFISCA is the first generic SIMD-based software countermeasure that can concurrently resist against Side-Channel Attack (SCA) and Fault Injection (FI). Its promising strength presented in a PRESENT cipher case study compared to software-based Dual-rail with Pre-charge Logic concurrent countermeasure. It has lower overhead, wider usability, higher protection. protection been using Correlation Power Analysis, Welch’s T-Test, Signal-to-Noise Ratio Normalized Inter-Class Variance testing methods. on-the-fly switch between its two modes of operation: The High-Performance High-Security by having only one instance cipher. This gives us flexibility trade performance/energy security, based on actual critical needs.
