After some investigation and comparison with other products, I was guessing if there are any plans to produce a Nitrokey (HSM & pro) with a tamper proof MCU, like the one that, as far I understand, is used on Yubiko keys (here they talk about using the NXP A700x chip on their keys: https://www.yubico.com/2015/02/big-debate-2048-4096-yubicos-stand/).
Thank’s for the details. I wasn’t aware of this MCU (and it’s not available yet). I didn’t read it thorough but if that MCU could become a replacement for smart cards needs to be confirmed. The article from Toms Hardware sounds like that but I don’t read this from the vendor’s description.
For our models which contain a tamper resistant smart cards, this MCU doesn’t bring real benefits. However for Nitrokey Start it would be interesting.
Nitrokey HSM’s MCU flash doesn’t contain any sensitive data. Instead cryptographic keys are stored in the smart card.
