Server-assisted signature plays an important role in all kinds of applications in electronic commerce. It can be applied to the settings where a user employs public network servers to help her execute digital signature operations. In this paper, the authors discuss a problem of how to construct forward secure single-server, multi-server and threshold server assisted signature schemes using Bellare-Miner Scheme and propose three signature schemes. In the single server assisted signature scheme, the user (signer) can employ a server to help her produce a signature.
