基于量子单向函数的量子门限签名方案

A (t,w) Quantum Threshold Signature Scheme Based on Quantum One-way Function

本文首次研究了量子签名中的门限签名问题,参考了LüXin和Feng Deng-guo的基于量子单向函数的签名协议,然后结合经典密码学中的Shamir门限方案提出了一个(t,w)门限量子签名的方案。方案是安全的(t,w)量子门限签名方案,安全性依赖于量子单向函数的存在,量子纠错码保证了量子态的真实性,量子一次一密保证了量子信息在信道的安全性。方案是对已知量子态的签名和验证。

In this paper, we investigated quantum digital signature and presented a （t,w） quantum threshold signature scheme, that is based on the LU Xin and Feng Deng-guo＇s protocol and Shamir threshold scheme. The security of scheme relies on the existence of quantum one-way functions, the authenticity of the quantum information is guaranteed by quantum error correction codes and security of the quantum information on channel is ensured by quantum one-time pad. This scheme is signature and validation on known quantum states.
