In the era of digital transformation, securing data on metaverse platforms poses significant challenges. This paper proposes Multiparty Space Sharing and Authentication (MSSA), a novel approach for secure user login and location access control within specialized metaverse platforms. MSSA leverages Quantum Multiparty Secret Computation (QMSC) integrated with a quantum blockchain network. This integration facilitates user verification within the presence of potentially untrusted metaverse authority. The underlying quantum blockchain employs a Delegated Proof-of-Stake (DPoS) consensus mechanism with a Borda voting scheme for authority node selection. By harnessing the principles of quantum cryptography, MSSA offers enhanced security against both classical and anticipated future quantum attacks. This research demonstrates the feasibility and potential of quantum blockchain for securing metaverse platforms, paving the way for secure and decentralized digital ecosystems.
在数字转型时代，保护元宇宙平台上的数据面临重大挑战。本文提出了多方空间共享与认证（MSSA），这是一种用于在专门的元宇宙平台内进行安全用户登录和位置访问控制的新颖方法。MSSA利用与量子区块链网络集成的量子多方秘密计算（QMSC）。这种集成有助于在存在潜在不可信的元宇宙权威机构的情况下进行用户验证。底层的量子区块链采用委托权益证明（DPoS）共识机制和用于权威节点选择的博尔达投票方案。通过利用量子密码学原理，MSSA针对经典攻击和预期的未来量子攻击都提供了增强的安全性。这项研究证明了量子区块链在保护元宇宙平台方面的可行性和潜力，为安全和去中心化的数字生态系统铺平了道路。
