Chaotic Encryption Research And Application Based On Hadoop

In an important part of network security,computer network technology plays a very important role.In recent years,people's dependence on Internet products has reached a new height,Internet products and for researchers working on cybersecurity issues,it not only represents convenience but also hides huge challenges.Cloud computing is not able to better serve cloud computing security because of its excessive data volume.How to optimize the existing chaotic cryptosystem in parallel to adapt it to the characteristics of cloud computing framework has profound research value.At present,researches on big data security issues at home and abroad have yielded many effective research results.The Hadoop distributed open source system brings new ideas to researchers who are studying cloud computing security topics.Parallel encryption of communication data is realized by the MapReduce mechanism in the Hadoop distributed system.It can effectively improve the security of data.In addition,the distributed file system of Hadoop prevents the information leakage problem of single-machine encryption from the mechanism.How to use Hadoop distributed file system,comprehensively balance the time and space complexity of the algorithm,and realize effective chaotic encryption of communication data,which is the main research content of this paper.Firstly,this paper analyzes one-dimensional text data and two-dimensional image data separately.After considering their respective data characteristics,the text will focus on the implementation of hyper-chaotic encryption system in text data.Secondly,in the image data,this paper will focus on the adaptation of two-dimensional data in big data systems,so as to solve the shortcomings of Hadoop distributed system that can only deal with one-dimensional data and chaotic encryption systems usually deal with two-dimensional image data.At the same time,this paper designs and implements an effective reading and encryption and decryption scheme for text and images,enriching the encryption form and encryption range of current cloud computing security topics.Finally,through the system demonstration and experiment,the feasibility of the MapReduce framework in the distributed parallel encryption system is proved,and the proposed algorithm has higher encryption speed than the traditional serial chaotic encryption.
