Dynamically reconfigurable 2D topology communication and verification scheme

摘要

Systems and methods for securing devices and encoding information in hardware and hardware arrangements are provided. Variations include switched networks included in conformal coatings applied to or connected to components to be protected or encoded. The decoding or security key data is included as part of the network layout and/or switching logic such that physical changes to the network prevent the recovery of the key data. Nodes in the network may include sensors meant to change node or network behavior based on sensor detection results.

1. A conformal coating having information embedded therein, the coating comprising: an insulating layer disposed on a component; an active layer including a switched network having a plurality of nodes controlled by a master device controller (MDC); wherein a node on the switched network is configured to have dormant, active, and routed states such that said node, upon getting an activation command from the MDC, said node enters the active state, upon getting a signal routing command, said node enters the routed state, and upon getting a de-activation command from the MDC, said node enters the dormant state; wherein the node provides information about itself to the MDC via the switched network in the active state and transmits a signal from the MDC to a subsequent node along a routed signal path in the routed state; wherein the routing command causes an active node to connect to a subsequent node in said network, said subsequent node being identified in the routing command; and where the embedded information includes a measurable property of a node in a signal path in the network.
