Bluetooth Frequency Hopping and Packet Transfer
Excerpt From Bluetooth Vulnerabilities (Part 2) Webinar
Learn more about the Bluetooth Frequency Hopping and Packet Transfer Presented by CTO, Dr. Brett Walkenhorst
In his explanation of Bluetooth communication protocols, Dr. Brett Walkenhorst emphasizes the protocols' set time intervals and the data transmission that takes place inside them. Devices switch frequencies after every connection event; in order to limit predictability and improve security, the precise frequency is chosen using a random sequence. Bluetooth connectivity is important for advertising channels. Once a connection is made, traffic visibility is limited. Bastille employs a wide-ranging radio frequency sensor to record and examine the complete spectrum, enabling the identification of linked devices and post-connection potential vulnerabilities.
