针对现有的量子代理签名协议,一个代理签名人只能代理一个原始签名人的情况,提出一个代理签名人可同时代理多个原始签名人的量子代理多重盲签名协议.以GHZ态为基础,利用秘密共享原理实现多个原始签名人对代理签名人的授权,并结合经典编码方法实现对量子比特串的签名和验证.由于签名的产生没有使用验证者的密钥,因此任意验证者可根据量子单向函数和酉操作的特性验证签名是否有效,使得协议的应用场景更加广泛.协议的安全性基于无条件安全的量子密钥分发和一次一密算法. Aiming at the existing quantum proxy signature protocol, a proxy signer can only proxy one original signer, and then proposes a multi-blind proxy signature scheme which can proxy multiple signers simultaneously. Based on the GHZ state, The principle of secret sharing is used to authorize the original signatories to proxy signatories, and the signature and verification of the qubit are combined with the classical encoding method.As the signatures are generated without using the verifier’s secret key, Quantum one-way function and unitary operation verify the signature is valid, making the protocol application more widely.The protocol security is based on unconditional secure quantum key distribution and a one-time algorithm.
