Hello!
I have the DNA 424 NFC tag and have encountered a problem. The tag is encrypted symmetrically. This means that i cannot share the key with other sources that would like to independently verify the scan (which is what my implementation wants to allow).
More specifically, the implementation will use blockchain and i cannot put the symmetrical key there because this key could be used to generate fake messages and make the whole system useless. Ideally the encryption would be asymmetrical, and the public key would be on the blockchain.
Does anyone know a solution to this problem?
