A multi-chaotic text encryption algorithm based on hadoop platform

Abstract

The invention discloses a multi-chaotic text encryption algorithm based on the Hadoop platform. The algorithm first divides the text to be encrypted into blocks, and transmits them to each Mapper respectively by the MapReduce parallel framework. The Mapper generates an input key according to the block data, and establishes The key generator generates a key sequence through the key and the size of the block data, and after preprocessing the key sequence, encrypts the block data with the key sequence, and then splices to obtain the encrypted text. The algorithm of the present invention breaks through the bottleneck of simply encrypting data on a single machine, optimizes the chaotic encryption method of the existing big data platform for the MapReduce framework and the principle of four-dimensional hyperchaos, and has more expansion potential for multi-dimensional data encryption than the existing method, and at the same time has It features high encryption efficiency and low memory usage.

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...

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
