ePrint Report: Correction Fault Attacks on Randomized CRYSTALS-Dilithium

Elisabeth Krahmer, Peter Pessl, Georg Land, Tim Güneysu

After NIST’s selection of Dilithium as the primary future standard for quantum-secure digital signatures, increased efforts to understand its implementation security properties are required to enable widespread adoption on embedded devices. Concretely, there are still many open questions regarding the susceptibility of Dilithium to fault attacks. This is especially the case for Dilithium’s randomized (or hedged) signing mode, which, likely due to devastating implementation …
