Abstract

We propose a secure threshold signature scheme without trusted dealer. Our construction is based on the recently proposed signature scheme of Waters in EUROCRYPT’05. The new threshold signature scheme is more efficient than the previous threshold signature schemes without random oracles. Meanwhile, the signature share generation and verification algorithms are non-interactive. Furthermore, it is the first threshold signature scheme based on the computational Diffie-Hellman (CDH) problem without random oracles.
