The Research Into Encryption Technique In The Military Vehicles Supervision System Based On Bluetooth

This paper gives the result making research into the encryption algorithm suit to Bluetooth and the realizationg of military vehicles supervision system based on Bluetooth.After the basic knowledge of cryptography, the standard of Bluetooth technology and its security setings are introduced briefly, the encryption algorithm in Bluetooth is analyzed particularly. The simulation program is compiled by using Visual c++ 6.0 on the Windows platform. The process of encrypting data in Bluetooth is implemented and the results of the program are analyzed. Several questions in encryption algorithm in Bluetooth, such as non-link key cheating, address cheating and EO are summarized and several improvements are also brought forward. According to the characteristic of Bluetooth, block ciphers AES is reworked. BT_AES adapted to Bluetooth is built. So more reliable data safeguards are gained, more extensive fields can be applied for Bluetooth. BT_ AES is realized in Visual c++ 6.0 on Windows and experimental data is obtained and discussed. It is proved feasible and efective to encrypt data in Bluetooth using BT_ AES.The encryption algorithm of this paper will not only be used in the field of military and business affairs widely but also provide reference for choosing the encryption algorithm to guarantee the security of data exchange when developing all kinds of WLAN.After the basic knowledge of Bluetooth technique standard,we optimize the project of military vehicles supervision system based on Bluetooth.The system is an advanced scientific management platform with automatization, network and efficiency,by use of which we can prevent the military vehicles from misappropriating, stealing and counterfeiting.It can also provide us enough ,true and realtime information about the vehicles and drivers.The system breaks through the tradition management methods .When we want to design other management systerm ,this systerm provide us a reference model. According to the difference of object and purpose ,we can optimize it suitably.This paper includes six chapters.Chapter one is the introduction, which gives a brief account of the background of study, the present of bluetooth security study, and the main tasks of this paper. Chapter two recovers the basic knowledge of cryptography fist. Several questions of non-link key cheating, address cheating are summarized and several improvements are brought forward.After simulation program of E0 is compiled, several questions and improvement are also brought forward.Chapter three. According to the characteristic of Bluetooth, block ciphers AES is reworked. BT_AES adapted to Bluetooth is built. By compiling simulation program of BT_AES, the encryption algorithm is proved feasible and effective. Chapter four.In order to make a preparation for the system design,we analyse the technology protocol of Bluetooth.Chapter five gives the optimization of military vehicles supervision system and the project of two key modules.monitor unit and vehicle unit. Chapter six gives a conclusion and the following research work in the future.
