Secure crypto module including conductor on glass security layer

A data handling electronic device comprising:

• a motherboard comprising a processor and a memory;
• a printed circuit board (PCB) comprising a connector that interconnects with the motherboard, the PCB comprising a PCB conductor on glass security layer comprising a first security trace directly upon a first toughened glass substrate;
• a secure crypto module comprising a daughter card electrically connected to the PCB, a shield comprising a metal shell that surrounds the daughter card, and a shield conductor on glass security layer directly upon an inner surface of the metal shell that faces the daughter card, the shield conductor on glass security layer comprising a second security trace directly upon a second toughened glass substrate;
• the daughter card comprising:
• one or more wiring layers each comprising a signal trace directly upon a dielectric layer, a crypto component, and a daughter card conductor on glass security layer comprising a third security trace directly upon a third toughened glass substrate;
• and
• a resistance monitor device electrically connected to the first security trace, the second security trace, and the third security trace, wherein a destruct feature of the crypto component is programmed in response to the resistance monitor device detecting the resistance across the first security trace, the second security trace, or the third security trace exceeds a respective predetermined threshold.
