A multi-chaotic text encryption algorithm based on Hadoop platform

Abstract

The invention discloses a multi-chaotic text encryption algorithm based on a Hadoop platform. The algorithm comprises steps: first blocking the text to be encrypted, which is transferred to each Mapper by the MapReduce parallel framework, the Mapper generating an input key according to the block data, establishing a key generator, generating a key sequence according to the size of the key and theblock data, pretreating the key sequence, encrypting the block data by using the key sequence, and then splicing the block data to obtain the encrypted text. The algorithm of the invention breaks through the bottleneck of encrypting data only in a single computer, optimizes the chaotic encryption method of the existing large data platform according to the MapReduce frame and the four-dimensional hyperchaos principle, and has more potential for developing the multi-dimensional data encryption than the existing method, and simultaneously has the characteristics of high encryption efficiency andlow memory occupation.

Description

technical field [0001] The invention relates to an encryption method, in particular to a multi-chaotic text encryption algorithm based on Hadoop platform. Background technique [0002] Facing the upgrading of network and application technology and the generation of massive information data, the current traditional stand-alone mode serial encryption method is limited by its hard conditions such as memory and processor size, and it is difficult to meet the requirements in terms of efficiency and memory usage. Encryption requirements for large amounts of data. For larger data environments, the computing load may far exceed the computing limit of a single computer. In response to the above disadvantages, it is becoming more and more important to improve data security protection. [0003] With the emergence of cloud computing, it provides a new idea for big data encryption. At present, the general method is to establish a cloud computing cluster platform. By packaging each com...

Problems solved by technology

However, this platform only provides us with a platform to effectively process massive data, but it lacks efficient encryption means, which leads to the danger of easy leakage of important scientific research data, business data or customer data and other private information

[0004] The existing technology only forms the key sequence through multi-level key transfer in the low-dimensional chaotic system, and the statistical characteristics of the generated sequence are not as good as the key sequence generated by the hyper-chaotic system; the existing technology does not divide the MapReduce parallel framework into a row Good combination of reading data and chaotic system generation principle, and lack of scalability for multi-dimensional data on the big data platform in the future
