主　　题：Continuous availability Verifiable delay function Zero-knowledge privacy Blockchain 

摘      要：The cloud computing technology has emerged,developed,and matured in recent years,consequently commercializing remote outsourcing storage *** increasing number of companies and individuals have chosen the cloud to store their ***,accidents,such as cloud server downtime,cloud data loss,and accidental deletion,are serious issues for some applications that need to run around the *** some mission and business-critical applications,the continuous availability of outsourcing storage services is also necessary to protect users outsourced data during ***,ensuring the continuous availability of data in public cloud data integrity auditing protocols leads to data privacy issues because auditors can obtain the data content of users by a sufficient number of storage ***,protecting data privacy is a burning *** addition,existing data integrity auditing schemes that rely on semi-trusted third-party auditors have several security problems,including single points of failure and performance *** deal with these issues,we propose herein a blockchain-based continuous data integrity checking protocol with zero-knowledge privacy *** realize a concrete construction by using a verifiable delay function with high efficiency and proof of retrievability,and prove the security of the proposal in a random oracle *** proposed construction supports dynamic updates for the outsourced *** also design smart contracts to ensure fairness among the parties ***,we implement the protocols,and the experimental results demonstrate the efficiency of the proposed protocol.
