In 1998, TNang et al. proposed two new (t, n)-threshold signature schemes with traceable signers that can withstand conspiracy attacks without attaching a secret number. However, this article will show that the proposed schemes are insecure by presenting a forgery attack on them. Any malicious attacker can generate a valid group signature for any message without knowing any secret keys of members in a group. (C) 1999 Elsevier Science B.V. All rights reserved.
