Abstract
A protective, anti-tamper coating and methods of coating creation and application are provided. The coating may include an elastomeric layer to allow for strippability/removal. The coating may also include a “smart layer” for tamper detection, imaging prevention, and tamper prevention or underlying device de-activation/alteration upon tamper detection. The coating may also include one or more ground planes around the smart layer and one or more frangible layers designed to interrupt or alter smart layer function in the event of a tamper attempt.
Claims20
An anti-tamper coating for a component, the coating comprising:
- a foundation layer that includes a thermal via and a component connection via, the foundation layer being disposed on the component;
- a smart layer disposed on top of the foundation layer, the smart layer including an active circuit component operably connected to the component through the component connection via;
- a capping layer disposed on top of the smart layer and equipped with a frangible portion such that a tamper attempt breaks the frangible portion, thereby causing physical damage to the active circuit component;
- where the active circuit component in the smart layer includes at least one of a logic device and a memory device.
