Abstract: | Sparkle is the first threshold signature scheme in the pairing-free discrete logarithm setting (Crites, Komlo, Maller, Crypto 2023) to be proven secure under adaptive corruptions.
However, without using the algebraic group model, Sparkle's proof imposes an undesirable restriction on the adversary.
Namely, for a signing threshold t |
