A method for establishing a link key between correspondents in a public key cryptographic scheme, one of the correspondents being an authenticating device and the other being an authenticated device. The method also provides a means for mutual authentication of the devices. The authenticating device may be a personalized device, such as a mobile phone, and the authenticated device may be a headset. The method for establishing the link key includes the step of introducing the first correspondent and the second correspondent within a predetermined distance, establishing a key agreement and implementing challenge-response routine for authentication. Advantageously, main-in-the middle attacks are minimized.
