Both BLE devices believe they are directly communicating with each other3 Elliptic Curve Diffie-Hellman algorithm provides a mechanism to exchange keys over an unsecured channel. Refer to the Elliptic Curve Diffie-Hellman (ECDH) slide for details4 An association model that requires both BLE devices to have display and “Yes/No” input capability5 Passkey entry and out-of-band pairing association models also provide protection against man-in-the-middle attacks.
