The main effcient scheme but needinga manager, proposed by W.G.Tzeng and Z.J.Tzeng inPKC'01, was investigated. We present an improved fullydistributed forward-secure signature scheme without amanager based on Tzeng-Tzeng Scheme. The improvement is achieved through a secure distributed key generation protocol and a modified key-evolving procedure. Thesecurity proof of our scheme is also given.
