Method for encrypting and decrypting information by means of ciphertext storage gateway

Abstract

The invention relates to a method for encrypting and decrypting information by means of a ciphertext storage gateway. According to the method for encrypting and decrypting information by means of the ciphertext storage gateway, data read by a client side are in a plaintext form, and the data are stored in a storage server in a ciphertext mode through the ciphertext storage gateway; the data are read out from the storage server in a ciphertext mode and are converted into data in a plaintext form on the client side application server through the ciphertext storage gateway. The method for encrypting and decrypting information by means of the ciphertext storage gateway specifically comprises the steps that (1) a storage space is mounted to the ciphertext storage gateway; (2) the ciphertext storage gateway is mounted to a cloud computing server; (3) a driving program is installed on the ciphertext storage gateway, and the driving program is called during access to all / mnt / oss files. The method for encrypting and decrypting information by means of the ciphertext storage gateway has the advantages that the cloud shield ciphertext storage gateway is used by enterprises for encrypting data during data storage, and data encryption is independent of carriers and containers; data leakage protection and enterprise application systems are combined perfectly, and the data security of the enterprises are effectively guaranteed; the method can be flexibly applied to various complicated kinds of network architecture more effectively and more flexibly.

Description

technical field

[0001] The invention relates to the field of gateways, and mainly relates to a method for encrypting and decrypting information by using a ciphertext storage gateway. Background technique

[0002] Conventional enterprise server architecture adopts plaintext transmission and plaintext storage. Cloud storage has the characteristics of high performance, large capacity, elastic expansion, and automatic management, which can meet the requirements of file service and backup, streaming media, digital video surveillance, behavior analysis, log monitoring, and historical data. Applications in retrieval, data mining and other fields. More and more Internet application developers deploy their applications on public clouds, using cloud computing servers and open storage servers provided by cloud service providers. The public cloud danger zone: partly due to the immaturity of cloud service provider technology; There are security risks due to the use of corporate data by ...
