Practical Threshold Signatures

Victor Shoup

Abstract

We present an RSA threshold signature scheme. The scheme enjoys the following properties: it is unforgeable and robust; in the random oracle model, assuming the RSA problem is hard; signature share generation and verification is completely non-interactive; the size of an individual signature share is bounded by a constant times the size of the RSA modulus.
