%X A very dangerous problem to a threshold group signature is forgeability, i.e. an authorized subset can impersonate another authorized subset to generate signature. A new threshold group signature based on Williams scheme is proposed in this paper, which is brief and nonforgeability. The scheme can possess anonymity and traceability at the same time. In this scheme, the secret transmission channel is not necessary and only a few parameters should be public. So it is efficient.
