Based on the literature [1] and [2],this paper present a new threshold signatures scheme with a special member among the signers,that is,only the signers which contain the special member can generate a valid signature.

Through the security analysis of a new(t,n) threshold signature scheme with a special member presented by Miao at the tenth youth communication conference,this paper proposes three kinds of forgery attacks,malicious SDC and the signaturer can forge a valid signature.

By using special generator of indecomposable module, we get some conclusions of short exact sequence and epimorphism of modules, which are the fundament of Hall polynomial of Hall algebra corresponding to tube category.

Applying special generators of an indecomposible module,we discuss some properties of module homomorphisms,and get the constitution of induced direct decomposition of L and its cokernel about homomorphism f:M h l →L.
