Securing Bluetooth Communications
Following the increasing confidentiality of data being transferred, many concerns have been raised as to whether Bluetooth transmission is adequately secure. The Bluetooth 2.1 standard introduces a new security mechanism called Secure Simple Pairing (SSP). However, to avoid man-in-the-middle attacks, SSP uses a 6-digit number for authentication. If a human error occurs while conducting visual verification, then data security could be breached. This paper presents an improved protocol to address this problem. This protocol not only secures consumer privacy, but also increases operational efficiency.
