SMS Encryption Research And Application Based On ANDROID

Personal privacy information leakage is a growing problem, with the rapid development of mobile communications technology and smart phone operating system, and how to effectively protect the privacy of mobile phone users, to address and improve the security of the mobile phone short message, become increasingly concerned about hot issues. The protection of information security is the most effective way is to encrypt the information source encrypted phone to become a dedicated phone undoubtedly increase the cost, can not meet the ordinary masses of information security, due to the limitations of the traditional phone information encryption can only rely on the hardware to accomplish urgent needs. Along with the popularity of the Android mobile phone users, based on the Android mobile phone software encryption possible to effectively encrypt SMS by using a variety of encryption algorithms, and then compare the comparative analysis, the optimal solution of the encrypted information to improve the efficiency of its encryption, this encryption Thoughts on information privacy protection in mobile phone communication is extremely important significance.This article briefly describes the status of the ANDROID operating system, the four major components of the system architecture and system to explain the advantages as well as the prospects for the development of ANDROID, and then details the development of key technologies required for SMS architecture and ANDROID SMS and SMS encryption method. Comparison of several currently popular encryption algorithm and its advantages and disadvantages, the use of mobile phones in the ANDROID platform simulator software development and algorithm analysis and comparison, the basic functions of SMS encryption simulate the performance of different encryption algorithm parameters.In this paper, the algorithm on a variety of information, comparison, analysis, based on the the ANDROID system under encryption algorithm to solve the problems of privacy in the communication process SMS stolen SMS in information extraction algorithm to cryptographic generate A new text content. And multiple algorithm encryption is applied ANDROID system SMS encryption algorithm depth study and discussion, to conduct a feasibility analysis for the application of a variety of algorithms and draw the appropriate method and the test of real data, and ultimately based on ANDROID SMS encryption software system.
