The Research Of Security Application Based On The Bluetooth KEY

In recent years, with the rapid expansion of the popularity of smartphones and users, more and more users begin to use mobile payment.Though mobile payment have changed our lives in many ways, from the previous shopping on the computer, and now we can shop on line by cell phone at anywhere and anytime,which make our life become more convenient and quick.To bring convenient for us at the same time, however, the user account stolen, information disclosure, mobile phone virus problems emerge in endlessly, so its potential security problems cannot be ignored.The most major problem of the current mobile payment is security problems.Based on the analysis of the existing mobile security problem,This paper proposes a new mobile payment solution based on the bluetooth KEY communication.The main research content is divided into the following four parts:First,introduce the background of the thesis, the current related research status at home and abroad, and the paper’s main content and structure arrangement.Second,related analysis of the theory research.This paper mainly introduces the bluetooth communication technology, and research of the current mainstream cipher algorithm. At the same time we analyze the advantages and disadvantages, and application scenario.Thirdly,the integrated design of the bluetooth KEY system.This paper mainly introduces the structure of the system and the determination of the scheme and the payment process of the system.We realized the design of the communication message between mobile terminal applications and the bluetooth KEY.And the paper analyzed the safety and feasibility of the system.Fourthly,the realization of bluetooth KEY system. we achieved the design and implementati on of keyboard input module,and the design and implementation of Bluetooth module,the design and implementation of display module,and the design and implementation of Chinese character library,and the design and implementation of flash storage module,and the implementation and optimization of AES encryption algorithm,and the design and implementation of mobile terminal application.Fifthly,system test and result analysis.This paper’s test is mainly divided into two parts.The basic test is used to test the correctness of the basic functions of the software,which is the most basic evaluation condition of the development of qualified or not.The test of edge and extreme condition is the detection of the stability of the system under the non conventional operation, such as the illegal character or the information input, which is aimed at testing the stability of the system.In the end,the paper summarized the research work of this project, and test and verify all basic functions of the system. The results show that the system can complete the expected design goal, realizing the combination of theory and application, which has certain application value.
