Abstract

Shared generation of secure signatures, called the threshold signatures, was introduced by Desmedt and Frankel in 1991. A threshold signature scheme is not only a threshold scheme, but also a signature scheme. Therefore, it should possess the properties of both threshold scheme and digital signature scheme. In this paper, we investigate conspiracy attacks on the Desmedt and Frankel's threshold RSA signature scheme. We also discuss the requirements of secure threshold signature scheme.
