摘要 |
<p>Various embodiments of devices and associated methods are described herein for authenticating electrical devices. In one aspect, an electrical device is provided comprising an interface configured to receive and transmit signals; a power line coupled to the interface and configured to provide a power signal thereto; and an authentication circuit coupled to the interface and the power line. The authentication circuit is configured to disable the power signal on the power line for a specified time period in response to an authentication request signal received at the interface and to provide an authentication response signal on the power line to represent the disabling of the power signal.</p> |
