<p>Embodiments of the systems, devices, and methods described herein generally facilitate the secure transmittal of security parameters. In accordance with at least one embodiment, a representation of first data comprising a password is generated (705) at the first computing device as an image or audio signal (710). The image or audio signal is transmitted (715) from the first computing device to the second computing device. The password is determined from the image or audio signal at the second computing device (725). A key exchange (730,740) is performed between the first computing device and the second computing device wherein a key (736,748) is derived at each of the first and second computing devices. In at least one embodiment, one or more security parameters (e.g. one or more public keys) are exchanged (744,750) between the first and second computing devices, and techniques for securing the exchange of security parameters or authenticating exchanged security parameters are generally disclosed herein.</p> |
