Abstract

At present, under the Shamir-based digital signature scheme, most of them still need a trusted center to participate in the distribution of sub-secrets(secret shares), lack of reverse supervision of group management by members, and lack of strong forward security. Under the premise of these problems, this paper proposed a new scheme, which had no trusted center participation, and could update multiple members, private keys regularly, and solved the problem of members joining and exiting. The scheme consisted of three parts: generating signatures, private key updates, member joining and exiting. The involved operations mainly included Lagrange interpolation calculation, which had a good time complexity, and realized de-trusting centralization. It regularly updates member private keys while keeping the public key unchanged, so as to realize the ability of member joining and exiting, thereby ensuring the integrity of messages and strong forward security.
