量子数字签名研究进展

Progress in Quantum Digital Signature Research

量子数字签名是量子理论与经典数字签名的结合,其目的是利用量子效应达到无条件安全的信息交互。介绍了目前提出的几种量子数字签名协议,详细分析了这几种协议的优缺点和效率,提出了量子数字签名协议设计的具体要求,并展望了此领域今后的发展方向。

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.
