Common digital signature scheme is based on public key infrastructure. Each node should keep a certificate, this makes digital signature scalable to large numbers of participation and relies on a trusted center. On the other hand, conventional group signature scheme cannot find which participant gives a error or forged sub-signature. The protocol we proposed in this paper features a none trusted center group signature scheme, which not only ensures high-level tolerance to the network attack, but also detects the suspicious node in the system. This protocol can be applied in ad hoc networks.
