Securing WiFi with Blockchain

Hi E2E,

Good day!

May I know if we have a module or IC that can support blockchain authentication? Also, do we have some documentation for it?

Looking forward to your response.

Best regards,

Franz

    HI Franz,

    We do not have any documentation or demonstration of how you would support blockchain authentication on the CC32xx or any other TI IC as far as I can tell. That being said, blockchain authentication could be possible to achieve, assuming that you can use some web service over HTTP/MQTT or some such to fetch the needed data from the blockchain. If you look at the steps laid out in this explanation:

    https://medium.com/blockchain-blog/blockchain-based-authentication-of-devices-and-people-c7efcfcf0b32

    The steps seem mostly the same as the usual RSA-based handshaking mechanism that our device supports for TLS. The only difference is that the public keys are fetched from the blockchain, instead of from the peer's signed certificate.

    If your customer has a method to allow the CC32xx to get this blockchain data through some networking API that can be invoked programmatically, then it should be doable. However, I do not know of what services are out there which support blockchain access, and whether or not they allow use of supported networking APIs. The customer will need to figure that out on their own.

    Regards,

    Michael
