how to protect sensitive data, such as key, in DA14681?

hi Dialog,

    I would to store sensitive data , a key of encryption or PIN code data, in flash or somewhere in DA14681.  Do you have any suggestion for protecting the data stored from hacking.   I know DA14681 does not have any secure area like trustzone.   thanks for your answer.

Hi nigelyang,

Hi nigelyang,

Probably you could check the crypto block and store your data in QSPI flash. Keep in mind the DA14682 and DA14683 are recommended for new designs. Why don’t use any of them? There is a DA14682/DA14683 Secure Boot Tutorial .

Thanks, PM_Dialog
