Abstract
Provided are a method of connecting BLUETOOTH® devices using a single BLUETOOTH® channel and a BLUETOOTH® device using the method. A public key may be exchanged via a predefined single BLUETOOTH® channel, thereby preventing a Man-in-the-middle (MITM) attack. For example, when an MITM attacker intercepts the public key and attempts to perform an attack on the other BLUETOOTH® devices, other BLUETOOTH® devices may also receive the public key via the single BLUETOOTH® channel. Accordingly, the other BLUETOOTH® devices may recognize that the MITM attacker attempts to carry out the MITM attack using a disguised address.
