藍(lán)牙作為日益使用廣泛的無線傳輸技術(shù)，其安全問題值得重視。藍(lán)牙安全機(jī)制可以用
軟件實(shí)現(xiàn)，也可以用硬件實(shí)現(xiàn)，但在對處理時間要求嚴(yán)格的應(yīng)用設(shè)備中，硬件實(shí)現(xiàn)效果更佳。本文在分析藍(lán)牙鏈路層安全機(jī)制的基礎(chǔ)上，探討了一種全硬件的實(shí)現(xiàn)方案，具有較好的應(yīng)用價值。

Abstract: As a popular wireless transfer technology,Bluetooth become more and more important especially its security problem.Bluetooth security architecture can be realized by either software or hardware,but in time-critical applications devices,a hardware implementation is preferable.This paper analyses the bluetooth’s link layer security mechanism,discusses a entirely hardware implementation project that have preferable application value.
