Bluetooth security mechanisms research Based on the AES algorithm modification

The encryption algorithm in the Bluetooth security mechanism authentication process. Analysis of current security risks based on the sequence of password encryption algorithm, proposed the idea of block cipher encryption. Discussed in detail the various types of attacks in the Bluetooth authentication process and put forward two kinds of preventive measures by the hardware and software. 128-bit AES encryption algorithm and improved so that it can be applied to relatively low computing speed and storage resources in a relatively small number of Bluetooth mobile systems. The test showed that the AES algorithm can be improved Bluetooth authentication process to provide a more reliable security guarantees.
