A(t_0,t_1,t,n)-Threshold Signature Scheme Based on RSA

This paper proposes a (t_0,t_1,t,n)-threshold signature scheme based on RSA. Compared with the existing (t_0,t,n)-threshold signatures, the scheme has the advantages as follows: (1) The scheme is based on the widely approved RSA signature scheme; (2) The public key and the verification of the signature are similar to those of the general RSA signatures; (3) Its security and efficiency have been improved.
