Quantum digital signature combines quantum theory with classical digital signature.The main goal of this field is to take advantage of quantum effects to provide unconditionally secure information exchange.A particular description of several quantum digital signature protocols is given in this paper.The advantages,disadvantages and efficiency of these protocols are analysed in detail.The basic demands of designing quantum digital signature protocol and the direction in its development are pointed out.
