Speech Chaos Encryption And Real-time Transmission Based On Android System

Since E.N.Lorenz discovered chaos in 1963 and now more than 50 years ago,chaos theory has been widely used in various fields.At the same time,chaos theory is also developing in these applications.In particular,after the chaotic dynamic system synchronization method is proposed,more and more experts and scholars are committed to applying the synchronization method of chaotic dynamical systems to the field of communications.Combining chaos theory with the communication system has become another research on chaos control.The trend is more a trend in the future.Many researchers have proposed many improvements in practical applications.With the popularization of the Internet and people’s attention to privacy,many substantial issues concerning network security and personal privacy have also appeared.Therefore,chaotic secure communication in the future has a very broad application prospect.This paper proposes a scheme for real-time encryption of speech using high-dimensional hyperchaotic systems and is implemented on the Android platform of mobile phones.The scheme firstly solves the chaotic system,and then recombines the obtained solution sequence to generate a new chaotic solution matrix.The matrix is used to scramble and scramble each frame of the real-time speech data,and the speech data encryption is sequentially deduced.In this paper,after deeply studying and thinking about the current status and development trend of current chaos theory,combined with the current wide-ranging communication technology,real-time speech encryption in the mobile phone platform proves the feasibility of the application of chaos theory in real life scenarios.This article mainly includes the following:1.The specific steps of the chaotic encryption scheme.A brief analysis of the dynamic characteristics of high-dimensional chaos and the use of four-dimensional hyperchaos secrecy algorithm are given in detail.The specific steps of applying the high-dimensional chaos security algorithm to real-time speech encryption are given in detail.2.Analysis of software and hardware architecture.Introduce part of the hardwarestructure and software architecture briefly,analyze the working flow and related principles of Android platform;analyze the composition of software architecture and how the components work together;detail the construction environment of the entire project and the steps required;3.Real-time speech chaotic security system implementation on Android platform.Describes in detail the entire process of collecting voice from the microphone and finally sending it out through the network,and gives a detailed description of how the specific scheme is implemented.In order to make the transmission of speech files more efficient after encryption by the chaotic algorithm,after referring to many file transmission schemes,the use of speex encoding compression greatly improves the quality of the restored speech files.4.The design of the network transmission part.After many tests and reference to the actual application scenarios of major companies,the system uses UDP transmission protocol;in the third chapter of the article briefly introduces the UDP protocol,and gives the reasons for the final selection of UDP protocol in the subject;5.Analysis of experimental results.On the basis of the above,the experiment on the actual platform was completed and the results of the experiment were briefly analyzed.
