Shared secret for wireless devices

摘要

In some examples, a device may include a communication interface configured to exchange signals with another device, and a computing component configured to autonomously calculate a centroid of a plurality of devices of which the device is a part, based at least in part on relative distances between the device and others of the plurality of devices and relative distances among the others of the plurality of devices, and autonomously establish the centroid as a shared secret.

主权项

1. A device, comprising:
a communication interface configured to exchange signals wirelessly with another device; and a computing component configured to:
autonomously calculate a centroid of a mutually identifiable plurality of devices of which the device is a part, based at least in part on first respective distances between the device and each of others of the plurality of devices and second respective distances between pairs of the others of the plurality of devices;autonomously establish the centroid as a shared secret without communicating the shared secret to the others of the plurality of devices; andtransmit a wireless signal encrypted with the shared secret to at least one of the others of the plurality of devices;wherein the at least one of the others of the plurality of devices has calculated the centroid based on the mutually identifiable plurality of devices.
