  • Arterial roadway traffic data collection using bluetooth technology
    Georgia Institute of Technology, 2011
    Co-Authors: Box Stephanie
    Abstract:

    The use of Bluetooth technology for gathering traffic data is becoming increasingly popular due to the large volume of data that can be gathered at a relatively low cost. The limited number of devices in Discoverable Mode and potential long discovery time of the Bluetooth devices creates an opportunity for evaluating the sensor array setup that can maximize the sample of devices identified. This thesis investigates several factors that have a significant impact on the quality of the data obtained using Bluetooth, including the number of Bluetooth readers, orientation of the Bluetooth antennas, position of the readers relative to one another, and the location of the Bluetooth stations. The thesis begins with an overview of Bluetooth technology and literature review on the use of Bluetooth in previous traffic studies. Next, the methodology for the setup of the Bluetooth system and the four tests performed to evaluate the factors affecting the quality of the data are described. Through the results of these tests, it was observed that a "flat" antenna orientation allows for the greatest detection range and that the walls of buildings can prevent detection of Bluetooth devices inside the buildings. In addition, using multiple Bluetooth readers per sensor array resulted in statistically significant increases in number of detections of single reader sensors, and horizontally separated sensor arrays were observed to be more effective than vertically separated sensor arrays. Finally, the thesis concludes with a summary of findings and a discussion of further research needs.MSCommittee Chair: Hunter, Michael; Committee Member: Guensler, Randall; Committee Member: Guin, Angshuma

  • An enhanced method for the existing Bluetooth pairing protocol to avoid impersonation attacks
    ScholarWorks@UTEP, 2009
    Co-Authors: Mendoza, Patricia A
    Abstract:

    As the use of the Bluetooth technology in wireless technologies such as computers, cell phones, personal digital assistants (PDAs), printers, digital cameras, PC peripherals, and headphones, among others, has enormously increased during this decade, it has also increased the need of employing a more secure and robust pairing protocol that protects the transfer of information between Bluetooth devices. The existing Bluetooth pairing protocol starts when a Bluetooth device is set to be in Discoverable Mode and it is found by another device. After this step is completed, it initiates the pairing procedure by sharing some important device information, then by connecting to the other device and exchanging several link keys, and finally, by authenticating the connecting device in order to make sure is a trusted peer. However, through this document it is shown that this existing Bluetooth pairing protocol has still some security flaws that have caused impersonation attacks. The impersonation attack is a big concern in Bluetooth security due that, in most of the cases, it directly allows the access to relevant information, such as private, confidential or even classified, and this attack is reached just by creating a connection which is fully formed from a Bluetooth pairing with a false device credentials. Due to the concern for this type of attack, this document focuses on the implementation of an additional step on the existing Bluetooth pairing and authentication process, which enhances the Bluetooth security and also avoids the impersonation attack. This additional step was added just after the final authentication stage that a Bluetooth device commonly performs, and it is based on the use of Digital Certificates and a Certificate Authority in order to ensure that the identity of the connecting device can be trusted. Moreover, this additional authentication method is also based on three security levels, which are divided by the type of device to be connected, the application of this Bluetooth device, and the capabilities to connect to internet in order to verify the Digital Certificate that is going to be used for authentication
