Security Enhancement Layer for Bluetooth
Nicolas Sklavos, Xinmiao Zhang · 2017
During the recent years, wireless networking technologies have achieved a significant role as telecommunications media because of their flexibility and convenience in numerous usage scenarios. Of the wireless technologies, Bluetooth (Bluetooth Special Interest Group, Bellevue, Washington, USA) [1] has become the default choice for low-cost, low-power, short-range, and personal area communications. It is specified by Bluetooth Special Interest Group (SIG) [2], an industry consortium established for developing and advancing the wireless technology. Originally, Bluetooth was only intended as a simple serial cable replacement for electronic devices. However, pres- ently the technology supports various more advanced functionalities, such as ad hoc networking and access point operation for Internet connections. The ongoing development extends Bluetooth with new features, including support for quality of service, higher data rates, multicasting, and lower power consumption. Currently, Bluetooth can be found in mobile phones, personal digital assistants (PDAs), laptops, printers, digital cameras, headsets, portable payment terminals (e.g., for facilitating credit card payments in restaurants), cars, and medical equipments. The application area expands as new products with the Bluetooth capability are constantly introduced [3].
