Threshold Implementations in Software: Micro-architectural Leakages in Algorithms

John Gaspoz Siemen Dhooghe

Abstrak

This paper provides necessary properties to algorithmically secure firstorder maskings in scalar micro-architectures. The security notions of threshold implementations are adapted following micro-processor leakage effects which are known to the literature. The resulting notions, which are based on the placement of shares, are applied to a two-share randomness-free PRESENT cipher and Keccak-f. The assembly implementations are put on a RISC-V and an ARM Cortex-M4 core. All designs are validated in the glitch and transition extended probing model and their implementations via practical lab analysis.
