Abstract

In 2004, Abe et al. proposed a novel threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme. They claimed that their scheme allows the base signature schemes to be based on sigma-protocols, including Schnorr’s signature scheme, or the claw-free trapdoor one-way permutations (TOWP). However, we discover that some signature schemes cannot be applied to it such as Schnorr’s signature scheme, or the base signature may be insecure.
