Embodiment 1

[0055] This embodiment provides a schematic diagram of the implementation principle of a data management method for a cloud storage system based on trusted timestamps, as shown in figure 1 As shown, the specific processing flow is as follows figure 2 As shown, the following processing steps are included:

[0056] Step S210, using the digital certificate of the user terminal to establish an SSL (SecureSocketsLayer, Secure Sockets Layer) secure channel between the TSA and the user terminal.

[0057] The user terminal initiates a connection request to the TSA carrying the user's PKI digital certificate, which carries the certificate DN (Distinct Name, unique identifier), validity period, extension options, etc. After receiving the connection request, the TSA obtains the PKI digital certificate carried in the connection request, and sends a certificate verification request carrying the PKI digital certificate to the LDAP directory server.

[0058] After receiving the certificat...

Embodiment 2

[0076] This embodiment provides a data management system of a cloud storage system based on a trusted time stamp, and its structural diagram is as follows image 3 As shown, including: user terminal, cloud storage system, TSA and LDAP directory server,

[0077] The user terminal is configured to send a data processing request carrying a trusted time stamp to the cloud storage system, and the trusted time stamp is signed with a certificate of an authoritative and trusted time stamp authority TSA; when the cloud storage system accepts the After the data processing request, execute the data operation instruction corresponding to the data processing request

[0078] The cloud storage system is configured to verify the trusted time stamp and the certificate of the TSA after receiving the data processing request with the trusted time stamp sent by the user terminal, and verify the trusted time stamp and the certificate of the TSA After the certificate verification is passed, the da...

Abstract

The embodiment of the invention provides a data management method and system of a cloud storage system based on a trusted timestamp. The method mainly includes the following steps: the cloud storage system receives a data processing request which is sent by a user client and carries the trusted timestamp signed through use of a TSA certificate; and the cloud storage system verifies the trusted timestamp and the TSA certificate and after the trusted timestamp and the TSA certificate pass the verification, the cloud storage system receives the data processing request and the user client executes a data operation instruction corresponding to the data processing request. Through the third-party trusted timestamp, the cloud storage system is capable of carrying out effective management and audit on user data and carrying out verification and recording and filing on data operation records of a user so that the security of user operations and the authenticity of cloud storage data are guaranteed and it is achieved that the data security of the user is guaranteed while the complexity of the service procedure of the cloud storage system is not increased.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a data management method and system of a cloud storage system based on trusted time stamps. Background technique [0002] Cloud storage is an extension of the concept of cloud computing. It refers to the collection of a large number of different types of storage devices in the network through application software to work together through functions such as cluster applications, grid technology, or distributed file systems. A system that jointly provides data storage and business access functions to the outside world. The core of cloud storage is the storage and management of big data. The cloud storage system can provide users with different types of application services by providing various types of interfaces, such as network hard drives, remote data backup application platforms, IPTV and video-on-demand application platforms, etc. Wait. At the same time, users of clou...
