Embodiment 1

[0042] The embodiment of the present invention proposes a secure cloud storage system based on a hybrid encryption mechanism, which efficiently encrypts and decrypts user data on the cloud storage system through a hybrid encryption technology based on RSA and AES. The management module is used to securely manage user keys to ensure user data security.

[0043] This embodiment provides a processing flow of a cloud storage data management method based on a hybrid encryption mechanism as follows: figure 1 As shown, the following processing steps are included:

[0044] Step S110 , the user terminal sends an SSL (Secure Sockets Layer, Secure Sockets Layer) secure connection establishment request carrying the user's digital certificate to the cloud storage system.

[0045] The above user's digital certificate carries the certificate DN (Distinct Name, unique identification), validity period, extension options and other content. After receiving the SSL secure connection request, th...

Embodiment 2

[0061] The processing flow of a method for a user terminal to download user data in a cloud storage system provided by this embodiment is as follows: figure 2 As shown, the following processing steps are included:

[0062] Step S210, the user terminal sends an SSL secure connection establishment request carrying the user's digital certificate to the cloud storage system.

[0063] The above user's digital certificate carries the certificate DN, validity period, extension options and other contents. After receiving the SSL secure connection request, the cloud storage system obtains the user's digital certificate carried in the SSL secure connection request.

[0064] Step S220, the cloud storage system uses the CA to verify the above-mentioned user's digital certificate. If the verification is passed, the cloud storage system receives the above-mentioned SSL secure connection request, and establishes an SSL secure channel with the user terminal; otherwise, if the verification ...

Embodiment 3

[0077] This embodiment provides a cloud storage data management system based on a hybrid encryption mechanism, which is characterized in that it includes: a user terminal and a cloud storage system,

[0078] The user terminal is used to establish an SSL secure channel with the cloud storage system, and send an upload data request to the cloud storage system through the SSL secure channel; establish a TCP connection with the cloud storage system, and pass the The TCP connection sends upload data to the cloud storage system;

[0079] The cloud storage system is used to establish an SSL secure channel with the user terminal, and after checking that the upload data request is legal, establish a TCP connection with the user terminal, and connect the user terminal through the TCP The uploaded data sent by the connection is divided into blocks and encrypted for storage.

[0080] Further, the user terminal is specifically configured to send an SSL secure connection establishment requ...

Abstract

The embodiment of the invention provides a cloud storage data management method and system based on a hybrid encryption mechanism. The method mainly comprises the steps that: an SSL safe channel is established between a user terminal and the cloud storage system, and the user terminal sends a data uploading request to the cloud storage system through the SSL safe channel; and after the data uploading request is checked by the cloud storage to be valid, TCP connection is established between the user terminal and the cloud storage system, the user terminal sends uploaded data to the cloud storage system through the TCP connection, and the cloud storage system carries out blocking and encryption storage on the uploaded data. By utilizing the SSL safe channel and the TCP connection, the encryption protection work of user data is completed by the hybrid encryption technology based on RSA and AES secret key algorithms, and the identity management of a user is improved by the introduction of a digital certificate of the user, so that the cloud storage system is capable of carrying out rapid and effective encryption and storage on user data, and the data safety of the cloud storage system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a cloud storage data management method and system based on a hybrid encryption mechanism. Background technique [0002] PKI (Public Key Infrastructure) is a system that uses public key technology and digital certificates to ensure system information security and is responsible for verifying the identity of digital certificate holders. It is widely used in online banking, e-commerce, e-government and other fields. A complete PKI system is composed of certification authority, KMC (Key Management Center, key management center), registration authority, directory service, security certification application software, certificate application service and other parts, among which CA (Certification Authority, certification authority) It plays a central role in the PKI system. [0003] The RSA public key encryption algorithm was developed in 1977 by Ron Rivest, Adi Shamirh and Len Ad...
