ePrint Report: Differential analysis of the ternary hash function Troika

Christina Boura, Margot Funk, Yann Rotella

Troika is a sponge-based hash function designed by Kölbl, Tischhauser, Bogdanov and Derbez in 2019. Its specificity is that it is defined over $\mathbb{F}_3$ in order to be used inside IOTA’s distributed ledger but could also serve in all settings requiring the generation of ternary randomness. To be used in practice, Troika needs to be proven secure against state-of-the-art cryptanalysis. However, there are today …
