“Attackers access military data through fencing supplier”

We know that traditional solutions to cope with this kind of threats are -

Encryption of the data

+ Decryption keys hidden somewhere on the device or net

+ Text-password protection of the personnel who handle decryption keys

Now, although little known as yet, we have a far more robust solution -

Encryption of the data, by quantum resistant cryptography where appropriate

+ Image-based login with which decryption keys are regenerated on-the-fly

Well, thinking about removing the password, by any chance, for removing the password vulnerabilities altogether? — It’s a good idea for getting rid of the password headache like removing the stomach for removing the stomach-ache altogether, if we can love to see the unlovable consequences, that is, the overall destruction of identity security as dissected here — “How to not see our weak digital identity further weakened” (updated 31May2023)

Thanks to Stiepan Aurélien Kovac for bringing me to this inspiring report.
