摘　　要：重点分析了蓝牙信息安全中鉴权和加密算法的原理、结构以及运算法则,对加密过程中存在的不足作了分析与研究,给出了针对E0加密的弱点有效的攻击手段.最后,提出了将DES算法用于蓝牙加密中的方案.The principle, structure and the operation of authentication and encryption in the Bluetooth were discussed. Meanwhile, the shortage of this process was analyzed and some effective attack methods to Eo weak points were given. In the end, a new scheme, which the data encryption standard（DES） was applied in the Bluetooth encryption, was put forward.
