Method and system for encrypting, decrypting and verifying cloud storage front end data

Abstract

The invention discloses a method and a system for encrypting, decrypting and verifying cloud storage front end data. The method comprises the following steps of automatically encrypting uploading files of a user, and decrypting the uploading files to guarantee privacy of the user; automatically verifying integrity of data stored in a cloud storage terminal according to a predetermined cycle so as to verify whether the data stored in the cloud are tampered or deleted. According to the method and the system, the defect of incapability of guaranteeing the cloud storage confidentiality and the data integrity is improved, and the reliability and the security of cloud storage are improved.

Description

technical field [0001] The invention belongs to the technical field of cloud processing, and in particular relates to a cloud storage front-end data encryption, decryption and verification method and system. Background technique [0002] Cloud storage refers to the use of underlying technologies such as network technology, computer resource virtualization, and distributed computing technology to virtualize, collaborate, and package a large number of different types of storage device resources through the network, and jointly provide data storage and access services to the outside world. The storage system architecture, as the basis of data services in the cloud computing framework, has received more and more attention, and has begun to be gradually applied and promoted on a large scale. [0003] However, the promotion of cloud storage still faces some problems, the most important of which is that because users store data in cloud storage services controlled by cloud storage ...

AI Technical Summary

Problems solved by technology

[0003] However, the promotion of cloud storage still faces some problems, the most important of which is that because users store data in cloud storage services controlled by cloud storage service providers, users lose control over data, and user data privacy and security , and completeness cannot be well guaranteed, mainly reflected in:

[0004] 1. The privacy of data stored by users cannot be guaranteed

Information security mainly includes: confidentiality, authenticity, integrity, unauthorized copying of information, and security of the parasitic system. Leakage, the solution to this problem is encryption, but users need to provide encryption algorithms, and the generation and storage of encryption keys are also complicated issues

[0005] 2. It is difficult to guarantee the integrity of cloud data

Data integrity refers to the consistency and accuracy of stored data. Technically, cloud storage can achieve effective data storage, backup, and recovery, but it cannot guarantee the commercial technology of cloud services. Cost issues cause user data to be deleted and destroyed.

The solution to this problem is that users regularly download and view files from cloud service providers, but this will increase the bandwidth pressure of cloud service providers and increase the complexity of users using cloud storage services
