面向分布式量子网络的匿名盲量子计算协议

Anonymous blind quantum computation protocol for distributed quantum networks

量子网络安全旨在研究分布式量子网络中通信和计算的安全性.本文研究了量子计算任务中的两个安全问题,即隐私性和匿名性.为此,本文提出了一种新的单服务器多用户匿名盲量子计算协议,利用在服务器和用户之间生成的匿名纠缠作为量子资源用于实现盲量子计算任务.匿名性、盲性和安全性分析表明所提出的协议在实现盲量子计算的同时保证了用户身份的保密.和现有的盲量子计算协议相比,本协议为盲量子计算增加额外的安全保障,也为其他匿名量子密码协议的设计提供了新思路.

Quantum cyber security aims to examine the communication and computation of security within a distributed quantum network.Two primary security concerns,privacy and anonymity,are typically investigated in quantum computational tasks.Therefore,this study proposes a state-of-the-art,single-server,multi-user anonymous blind quantum computation protocol,wherein the anonymous entanglement shared between the server and user is utilized as a quantum resource for blind quantum computation tasks.The anonymity,blindness,and security analyses demonstrated that the proposed protocol can perform blind quantum computation tasks while maintaining the confidentiality of the user identity.Compared with conventional blind quantum computation protocols,this protocol provides additional security for blind quantum computing and serves as a novel design idea for anonymous quantum cryptography protocols.
