Threshold Ring Signatures

Glossary-Start

What is Threshold Ring Signatures?

Unlike standard “t-out-of-n” threshold signature, where t of n users should collaborate to decrypt a message, this variant of a ring signature requires t users to cooperate in the signing protocol. Namely, t parties (i1, i2, …, it) can compute a (t, n)-ring signature, σ, on a message, m, on input (m, Si1, Si2, …, Sit, P1, …, Pn).
