Anonymous blind quantum computation protocol fordistributed quantum networks

Abstract

<p indent="0mm">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.
