Description

This lecture covers the security aspects of Bluetooth pairing protocols, focusing on Bluetooth 2.0 and the improved Bluetooth 2.1 with Secure Simple Pairing (SSP). The instructor explains the challenges of key recovery, passive and active attacks, and the need for secure key establishment. The lecture delves into the Diffie-Hellman key exchange, authentication stages, and the use of cryptographic functions like HMAC and PRF. Different pairing variants such as numeric comparison and JustWorks are discussed, highlighting the importance of user-friendly and device-friendly security measures.
