Abstract
In one aspect, a system component includes a printed circuit (PC) board on which plural conductive ink segments are disposed. The system component also includes a sealed housing that houses the PC board. The plural conductive ink segments define a bit pattern to establish a key.
Claims20
A device, comprising:
- plural system components comprising at least a processor and storage accessible to the processor;
- plural conductive ink segments that define a bit pattern to establish an encryption key for use by one or more of the plural system components, each conductive ink segment comprising respective first and second ends;
- and
- a respective pin disposed at each first and second end of each conductive ink segment, wherein the device attempts to send electricity through each respective conductive ink segment via the respective pins disposed at the respective first and second ends of each respective conductive ink segment.

A method, comprising:
- disposing plural conductive ink segments on a printed circuit (PC) board, the plural conductive ink segments defining a bit pattern to establish a key;
- and
- disposing the PC board within a protective housing of a device;
- wherein the disposing the plural conductive ink segments on the PC board comprises disposing at least a first conductive ink segment on the PC board with at least one break in the first segment between respective ends of the first segment that are connected to respective pins on the PC board.
