摘要
To prevent active attack, we propose a new threshold signature scheme usingself-certified public keys, which makes use of hash function and discrete logarithm problem. Thescheme has less commutnication and computation cost than previous schemes. Furthermore, the signatmeprocess of the proposed scheme is non-interactive.
