This site is all about my assembly bound temporal physical fingerprinting project project The main idea is to prove a board’s identity from how it’s built and how it behaves over time, not just from a label or number or anything like that
main stuff
Hours ive spent on it so far
This is the main test pcb im making right now, its supposed to be able to run tests on if there is a timing difference between a trace that has an slowdown in the path vs one that does not.
something that can figure out if a pcb was swapped with a different one
I write down how the fingerprint of the board changes across hours and days. The goal im hoping for is to be able to show that a real board leaves a trail over time that a fake or exact replica can’t copy without spending lots of money. im going to see if the keys can be store into a server because it cnt be only hardware based, also have multiple variable pcb's
I build a pcb that keeps the measurements around the same. Same power source, around same temperature, same tools, so the fingerprints are real and not different from the different things.
