Systems and methods that facilitate introducing devices having digital characteristics to one another, to mitigate a man-in-the-middle attack. A keytote component supplies initial session keys for communication between devices, and includes a plurality of interfaces that can facilitate such communication. The keytote component can receive a key from a first device via one of a plulrality of communication interfaces associated with the keytote component. The user can then physically carry the keytote component to the vicinity of a second device for transferring the key thereto. As such, a man-in-the-middle attack can be mitigated, as an encrypted channel can be established in an insecure environment.
