The vulnerability of the Bluetooth BR/EDR encryption key negotiation protocol, which stems from the use of cryptographic algorithms with defects, allows a perpetrator to carry out a “man-in-the-middle” attack, interfering with the encryption setup process for BR/EDR connections and reducing the length of the encryption key used.

The vulnerability of the Bluetooth BR/EDR encryption key negotiation protocol lies in the use of cryptographic algorithms that contain vulnerabilities. Exploiting this vulnerability allows a malicious actor, operating remotely, to carry out a “man-in-the-middle” attack, interfere with the...
