I have a product in the field, Chinese clones are on the market using my firmware that was pulled via voltage glitch.
Two things,
1. You know you’ve made it when there is a Chinese clone of your product.
2. I’ll never use that chip again.
- sokoloff 7y agoWhat chip (family) would you use instead if firmware protection is important to your application?
- SlowRobotAhead 7y agoDepends. But the simple fact is if it’s REALLY important; you had better be doing it online and passing the result to the device. I could tell you about hardware security modules (HSM) or the new ARM trustzone for small micros, but I’m designing new products so that if I handed you the source - you still can’t clone a board. That requires a connection to a better trusted device.
