 Hello and welcome to this video about BLE security with STM32WB. I will start by describing the basic security concepts in Bluetooth Low Energy. Then we will move to more practical part, where I describe the security-related API that is used on the user application side in STM32WB. By the end of this video, you will be able to distinguish various protocol layers inside BLE stack that are responsible for security. You will know the difference between legacy pairing and secure simple pairing. You will understand the pros and cons of various pairing methods, and you will understand the requirements and threats that can happen in BLE systems. In the hands-on part, we will get a real-life experience with the security features mentioned during the theory. We will start by creating a simple BLE application for STM32WB, and we will do that from scratch in the QPamex. The application is very simple. It can advertise. We can connect to it with a BLE over Android or iOS phone, and this project will serve as a code base for all the future tests. We will test most of the pairing methods, so JustWorks, Passkey Entry, Numeric Comparison, and Out-of-Band Pairing over NFC. And at the end, we will test also other features like bonding and authorization.
