摘　　要：量子信息具有测量即是一种固有的破坏性过程的特性,这一特征在互补性原则中最为明显,而其互斥性表现为相互不相容的可观测对象不能同时被测量。文章利用此特性首先提出了一个关于量子可证明删除协议的正式定义,接着构造了基于“熵删除”的密码学原语,本质上都允许一个经典可验证的量子可证明删除,该协议允许客户端确信一个样本数据集已被不可信方删除,并且利用全同态加密设计和改进可证明删除协议,它可以在不可信的服务器处理加密数据,处理完成后向客户端证明数据已删除。最后,作为本协议的一个应用构造了量子可证明删除隐私保护方案,研究结果表明,方案能保证个人信息在区块链、云分布存储等应用的永久加密。Quantum information has the property that measurement is an inherently destructive process.This feature is most apparent in the principle of complementarity,which states that mutually incompatible observables cannot be measured at the same time.This paper proposes a formal definition of quantum certified deletion,constructes LWE-based cryptographic primitive,essentially allows a classic of verifiable proven to remove the protocol allows a client is convinced that a set of sample data were deleted untrusted parties,and uses the homomorphic encryption design and improvement to quantum certified deletion protocol,Which can process encrypted data on an untrusted server and prove to the client that the data has been deleted.Finally,as an application of this protocol,a privacy protection base on quantum certified deletion scheme is constructed.The research results show that this scheme can guarantee the permanent encryption of personal information in blockchain,cloud distributed storage and other applications.
