摘      要：Threshold signature is an important branch of the digital signature scheme,which can distribute signature rights and avoid the abuse of signature *** the continuous development of quantum computation and quantum information,quantum threshold signatures are gradually becoming more ***,a quantum(t,n)threshold group signature scheme was analyzed that uses techniques such as quantum-controlled-not operation and quantum ***,this scheme cannot resist forgery attack and does not conform to the design of a threshold signature in the signing *** on the original scheme,we propose an improved quantum(t,n)threshold signature scheme using quantum(t,n)threshold secret sharing *** analysis proves that the improved scheme can resist forgery attack and collusion attack,and it is *** the same time,this scheme reduces the level of trust in the arbitrator during the signature phase.
