Systems, devices, and methods for securely transmitting a security parameter to a computing device

摘要

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 at the first computing device as an image or audio signal. The image or audio signal is transmitted 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. A key exchange is performed between the first computing device and the second computing device wherein a key 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 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.

1. A method of transmitting one or more security parameters to a first computing device from a second computing device, the method performed at the second computing device, the method comprising:
receiving an audio signal, wherein the audio signal is a representation of first data, the first data comprising a password, wherein the password is not derived from a security parameter stored on the first computing device; determining the password from the audio signal; and performing a key exchange with the first computing device over a communication channel between the first and second computing devices, wherein second data is exchanged between the first and second computing devices in accordance with a key exchange protocol, such that a key, other than the one or more security parameters, is derived at each of the first and second computing devices using the password, and wherein the one or more security parameters is transmitted to the first computing device during the key exchange; wherein said performing further comprises
computing a confirmation value based on at least the one or more security parameters, and using the key derived at the second computing device, andtransmitting the confirmation value to the first computing device, wherein the one or more security parameters are authenticated when the confirmation value is successfully verified at the first computing device; and wherein the one or more security parameters comprise one or more public keys stored on the second computing device.
