摘　　要：本文提出了半量子群代理盲签名方案,其中签名验证者和部分代理签名者仅配备部分量子能力.该方案在保证原始消息拥有者的原始消息内容对原始签名者、签名验证者、代理签名组和帮助完成签名过程的可信第三方都是盲的基础上实现原始签名者授权代理签名组对其进行签名.经详细证实,该方案拥有不可伪造性、不可否认性、完全的盲性以及安全性.由于签名验证者和部分代理签名者都仅配备部分量子能力,比起许多已被提出的量子群代理盲签名方案,该方案具有更广泛的签名应用场景.In this study,we propose the semiquantum group proxy blind signature scheme,in which the signature verifier and some proxy signers only possess limited quantum capabilities.On the basis that the original message content of the original message owner is blind to the original signer,the signature verifier,the proxy signature group and the trusted third party helping complete the signing process,this scheme can accomplish the goal of the original singer authorizing the proxy signature group to sign this original message.This scheme is proved to have unforgeability,non-repudiation,complete blindness and security.Since the signature verifier and some proxy signers only possess limited quantum capabilities,compared with many existing quantum group proxy blind signature protocols,this scheme has a wider range of signature application scenarios.
