Key Negotiation Downgrade Attacks on Bluetooth and Bluetooth Low Energy

Our new paper Key Negotiation Downgrade Attacks on Bluetooth and Bluetooth Low Energy will appear in the ACM Transactions on Privacy and Security.

Our paper extends our previous work on the KNOB attack on Bluetooth BR/EDR to Bluetooth Low Energy (BLE), presents an updated evaluation of the KNOB attack for Bluetooth BR/EDR and discusses some of the countermeasures put in place by vendors such as Google and Apple after the disclosure of the KNOB attack and the amendment of the Bluetooth standard.
