The encryption of existing norms which used by bluetooth can be cracked. A new Bluetooth security improvement program to enhance data security which provides by the existing Bluetooth standard. By analyzing Bluetooth information security mechanism, algorithm of each of its part and steps of achieving the algorithm are explored in detail and security of the existing Bluetooth regulations are evaluated. Targeted at its shortage, a new security mechanism is constructed using DES algorithm to meet the requirements of application of Bluetooth with higher security.
