Embodiment 1

[0037] A data encryption system for storing and interacting between tenants and cloud servers according to the present invention, its structure includes a control terminal C, a key manager KM, and a key storehouse R. The control terminal C is provided with a security board inside, and the control terminal C and the key The manager KM communicates with each other, and the key manager KM communicates with the key store R;

[0038] The control terminal C is used to store and communicate with the tenant and the cloud server. The control terminal C receives the tenant's data file request information; obtains the data encryption key from the key manager KM, and performs encryption and decryption operations on the data file in the security board. Send the ciphertext of the data file to the cloud server for storage or transmit the plaintext of the data file to the tenant in a secure manner;

[0039] The key manager KM is used to communicate with the control terminal C, and generates t...

Embodiment 2

[0044] A data encryption method for storage interaction between a tenant and a cloud server according to the present invention uses a data encryption system to realize data encryption for storage interaction between a tenant and a cloud server, comprising the following steps:

[0045](1) The tenant submits a registration request to the certification center CA in the cloud computing environment and submits the required identification materials. After the certification center CA passes the verification, it issues a digital certificate to the tenant and saves it;

[0046] (2) File request: the tenant sends a data file request to the control terminal C, and the data file request is to upload the data file on the tenant to the cloud server for storage;

[0047] (3) Key request: After the control terminal C authenticates the identity of the tenant in the authentication center CA, the control terminal C forwards the data file request information to the key manager KM to request the da...

Embodiment 3

[0053] A data encryption method for storage interaction between a tenant and a cloud server according to the present invention uses a data encryption system to realize data encryption for storage interaction between a tenant and a cloud server, comprising the following steps:

[0054] (1) The tenant submits a registration request to the certification center CA in the cloud computing environment and submits the required identification materials. After the certification center CA passes the verification, it issues a digital certificate to the tenant and saves it;

[0055] (2) File request: the tenant sends a data file request to the control terminal C, and the data file request is for the tenant to access the data file stored in the cloud server;

[0056] (3) Key acquisition: After the control terminal C authenticates the identity of the tenant in the certification center CA, the control terminal C forwards the data file request information to the key manager KM, and the key mana...

Abstract

The invention discloses a data encryption system and method for interaction between tenants and a cloud server memory, and belongs to the technical field of computer data encryption. In the data encryption system, a control terminal is used for being in communication with the tenants and the cloud server memory, and receiving data file request information of the tenants; a data encryption key is obtained from a key manager, encryption and decryption are conducted on data files in safety board, and data file ciphertext is sent to the cloud server memory, or data file plaintext is transmitted to the tenants; the key manager is used for being in communication with the control terminal, generating the data encryption key, sending the data encryption key to the control terminal and sending the data file request information to a key storage; the key storage is used for safely storing the data file request information sent by the key manager. According to the data encryption system and method for interaction between the tenants and the cloud server memory, safety protection of tenant data is achieved through usage of tenant identifications and a symmetric cryptosystem encryption algorithm, intensity and complexity of key management can be reduced, and isolation of the tenant data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer data encryption, in particular to a data encryption system and method for storing and interacting between a tenant and a cloud server. Background technique [0002] The SaaS multi-tenant application model is an important model of cloud computing. Once this difference from the traditional software service method is proposed, it has attracted the attention of the academic and industrial circles. The fundamental reason lies in the infrastructure construction, Centralized implementation of application software development and operation and maintenance service providers improves the utilization efficiency of resources and the professionalization of operation services, and the service quality and comprehensive benefits are significantly improved. [0003] However, in multi-tenant application scenarios, the data security and privacy issues of multi-tenant applications stem from the characteristics of se...
