BLUFFS (Bluetooth Forward and Future Secrecy Attacks and Defenses) is an architectural weakness affecting Bluetooth BR/EDR devices implementing Secure Simple Pairing and Secure Connections under Bluetooth Core Specification versions 4.2 through 5.4. A man-in-the-middle attacker can interfere with encryption-procedure initiation to force negotiation of a reduced encryption-key length. The resulting short key may be feasible to recover, enabling compromise of the confidentiality and integrity of the Bluetooth link.
