Parallel encryption and decryption method for dynamic data under large data environment

Abstract

The invention discloses a parallel encryption and decryption method for dynamic data under a large data environment. Under the large data environment, according to the method, parallel encryption and decryption operations on a large amount of dynamic data stream generated on a network are achieved. According to the method, a general computer GPU is used for completing the data encryption and decryption processes in a parallel mode. According to the dynamic data transmission rate, the data processing concurrent width is adjusted self-adaptively, and on the basis that information safety is guaranteed, open operation of encryption and decryption is realized.

Description

technical field

[0001] The invention belongs to the technical field of information security and the field of parallel computing, relates to parallel processing of data encryption and decryption, and in particular to a large data-oriented dynamic data encryption and decryption parallel processing method. technical background

[0002] 1. The amount of data involved in big data is huge, and generally cannot be processed by traditional data tools within a reasonable time. The processing of traditional big data generally relies on cloud computing to provide a large amount of computing resources, and adopts the method of batch processing. Traditional big data processing has the following problems:

[0003] a. Occupy a lot of CPU hardware resources.

[0004] b. Using distributed computing, it takes a lot of time to communicate between computers.

[0005] 2. GPU parallel computing is a parallel solution that uses GPU to complete computing tasks. Since a unit of GPU has much highe...
