| 摘 要： | 蓝牙作为一种短距离无线通信技术具有诸多优势,但蓝牙在设计之初对安全性的考虑不周导致了它的应用受限。分析了蓝牙的安全机制,阐述了蓝牙在认证鉴权方面的问题和E0流加密算法存在的缺陷。DES属于分组加密算法具有很高的安全性,为蓝牙加密算法的改进提供了一个新思路。最后利用VC6.0来仿真基于蓝牙的DES算法,结果说明了其具有更高的安全性能。

| Abstract: | Bluetooth as a short-range wireless communication technology has many advantages.But at the beginning of Bluetooth＇s design,it was not considered safe enough,which led to its limited applications.This paper analyzes Bluetooth security mechanism,describes the questions of authentication and the deficiencies of E0 encryption algorithm.DES is block cipher with high security,which provides a new method for the improvement of Bluetooth encryption algorithm.In the end,VC6.0 is used to simulate DES algorithm based on Bluetooth,and the result shows a higher security degree. |
