Abstract

The present invention provides a chaotic parallel data encryption method based on virtual computing and data optimization, including: S1, establishing a chaotic equation, dividing the data, obtaining the divided data sets, and determining the virtual computing core set; S2, judging the The difference between the data set and the virtual computing core set, according to the size of the difference and zero, determine the virtual computing core set in the execution state, and establish a static mapping relationship between the data set and the virtual computing core in the execution state; S3, according to The physical computing core set in the parallel system establishes the execution state physical computing core set, and establishes the static mapping relationship between the execution state virtual computing core set and the execution state physical computing core set, and the execution state virtual computing core obtains the chaos equation key and perform data encryption. The encryption method proposed in the embodiment of the present invention can make full use of the physical computing core according to actual needs, that is, make full use of the computing resources of the parallel system.

Description

technical field [0001] The invention relates to the technical fields of data security and network security, in particular to an encryption method for chaotic parallel data based on virtual computing and data optimization. Background technique [0002] With the development of the Internet and cloud computing technology, people's lives rely more on the Internet. And the data stored and transmitted on the Internet also has security issues. How to ensure the security of these data is of great significance to countries, enterprises and individuals. The protection of sensitive and private data is also an urgent problem to be solved in the development of technologies such as the Internet of Things and cloud computing. [0003] Therefore, in order to ensure the security of data, the existing data encryption method is: use Logistic chaotic map and Fibonacci sequence to mix, divide the data into odd and even numbers in the dual-core processor according to the order of bytes, and div...

Problems solved by technology

[0004] The defect of the above-mentioned data encryption method is: the data encryption method directly distributes the data on the physical computing core for calculation

Although parallel encryption can be achieved in dual-core processors, data division is based on the physical computing cores of dual-core processors. When the underlying physical computing cores change, the physical computing cores cannot be effectively utilized.

For example, when the number of underlying physical computing cores changes to 4 or 8, only 2 of them are used for encryption processing without using the remaining 2 or 6 for encryption processing; and when the number of underlying computing cores becomes When 1, encryption processing cannot be performed
