一种基于区块链的安全云存储方案设计

云存储方式是将数据上传到云服务器中,以此来减轻本地存储的负担。然而,把数据存储到不受信任的第三方云服务器上,可能导致一些数据安全隐患的出现,其中最典型的是数据的完整性问题和隐私问题。针对数据完整性问题和隐私问题,提出一种基于区块链的云存储方案。该方案利用区块链的梅克尔树属性、匿名性、不可篡改等特点构建安全云存储系统,有效地解决了数据完整性问题和隐私保护问题。

DESIGN OF A SECURE CLOUD STORAGE SCHEME BASED ON BLOCKCHAIN

Cloud storage method is to upload data to the cloud server,reducing the burden of local storage.However,storing data on untrusted third-party cloud servers can lead to some data security risks,the most typical of which are data integrity issues and privacy issues.In order to address the above two problems,we propose a novel cloud storage scheme based on Blockchain.In the scheme,the Merkle tree attribute and the characteristics of anonymity and tamper resistance of the Blockchain were used to construct the secure cloud storage system,thereby effectively solving the data integrity and the privacy protection problems.
