Method for accessing and uploading data in data storage system

Abstract

The invention provides a method for accessing and uploading data in a data storage system. The method of accessing data comprises the following steps: a client side initiates an access request message for access to a file; an authentication server determines the security level of the file according to feature information of the file in the access request message after receiving the access request message; if the security level of the file requires to carry out a smart key equipment certification process, the authentication server informs the client side of utilizing smart key equipment to carry out the smart key equipment certification process; after receiving information for the smart key equipment authentication, the client side carries out the smart key equipment authentication process; if the authentication server approves the smart key equipment authentication, the authentication server sends a notification message to a storage server; the storage server allows the client side to access to the file; the client side acquires the file, and decrypts the data of the file by utilizing a decryption key in the smart key equipment, so as to obtain the decrypted data.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method for accessing and uploading data in a data storage system. Background technique [0002] Cloud storage is a new concept extended and derived from the concept of cloud computing. It is a technology for remote file access and file sharing. Cloud storage typically places data in external storage pools rather than on-premises data centers or dedicated remote sites. Using cloud storage services to put data in the cloud can save investment costs, simplify complex setup and management tasks, and facilitate access to data from more places. [0003] Cloud storage has become a trend of future storage development. Hundreds of millions of users are uploading or accessing various files to their own cloud storage space every day, but with the development of cloud storage technology, more and more applications combining various search, application technology and cloud storage U...

Problems solved by technology

Hundreds of millions of users are uploading or accessing various files to their own cloud storage space every day, but with the development of cloud storage technology, more and more applications combining various search, application technology and cloud storage Users can quickly upload photos, videos or personal logs taken with their mobile phones or tablets to the network disk through cloud storage at any time, so that they can quickly access the uploaded data in different places or even instantly through the WEB or PC client in the future. The data is stored in clear text on the server side of the cloud storage. There are many confidential files or user privacy in these files. Once the personal cloud storage space is cracked, sensitive information will be leaked; in addition, in terms of operation and maintenance costs, the It is too difficult to manage private key encryption for all files on the server
