Embodiment

[0142] In order to evaluate the performance of the present invention, the time overhead of some algorithms is measured in the following embodiments.

[0143] In order to evaluate the system overhead, the implementation process adopts the open source DigitalNote platform based on the CryptoNote protocol, and completes the implementation of relevant algorithms according to the system requirements. In order to evaluate the system overhead, the test chain experiment environment is deployed locally during the implementation process, among which, three miner nodes and three wallet terminals are deployed locally for experiments, and the time overhead of the main algorithm of the main steps of the system is analyzed, and Measurement of time overhead. Among them, T File Time overhead for client file processing, including file hash operation time, file block operation time, and file block upload time; T Tx The time to generate a transaction operation for the user side, including the t...

Abstract

The invention discloses a privacy protection method of a distributed cloud storage system, comprising a user, a miner, a storage provider, system initialization, file uploading, file sharing, file downloading, file deletion and the like. The invention combines the distributed cloud storage system with the block chain technology, and regards the file ownership processing process as the transactionprocessing, thereby realizing the privacy protection of the file ownership processing process in the distributed cloud storage system, including the hiding of the sender, the receiver and the transaction content. In addition, the invention can effectively resist the replay attack and the data forgery attack while ensuring the privacy of the user.

Description

technical field [0001] The invention relates to a distributed storage technology, in particular to a privacy protection method for a distributed cloud storage system. Background technique [0002] With the development of cloud storage technology, users can easily outsource data to the cloud, and perform operations such as sharing, downloading, and modifying data in the cloud. However, the traditional cloud storage model almost exclusively relies on centralized cloud servers to provide services. This model based on client-server trust has some inherent weaknesses and is vulnerable to attacks, such as man-in-the-middle attacks, malware attacks, central A standardized server may also cause data unavailability and leakage of user privacy due to technical failures. Distributed cloud storage can better solve these problems. Common distributed cloud storage systems include HDFS, Ceph, Pangu, etc. The distributed cloud storage system removes the centralized server and ensures the...
