Design And Implementation Of Bluetooth File Transfer Application In The Embedded System

In recent years, with the rapid development of electronic communication, especially the fast popularization of wireless communication and the ripe of semiconductor chip technology, the short distance wireless communication have already been paid to more and more attention. Bluetooth technologies that with low cost, low consumption, offering pronunciation data transmission become the focus .Everybody pays close attention to it at the same time. It provides convenience high-efficient wireless communication, makes data transmission and exchange between embedded apparatus unusually convenient. The amount of consumption electronic products based on it increases rapidly. Meanwhile, some security problems in embedded wireless devices expose gradually too. The security problem of bluetooth technologies in the embedded system has caused people's extensive concern.This thesis mainly studies the security problem of bluetooth data transmission in the embedded system, and has proposed a safe solution of bluetooth file transmission based on XSbase255 embedded developing platform. Based on the detailed analysis and study of the existing bluetooth safe model, this thesis describes the design and realization of the encryption file transfer between the embedded apparatus, including the discernment of the apparatus, encryption and deciphering of the data etc. And according to the actual conditions of the proposed safe scheme, this thesis suggested to customize the bluetooth agreement inn BlueZ which improves the stability and efficiency of the solution to the greatest extent.
