Other governments take note: this is what good electronic security looks like.

Other governments take note his is what putting all your eggs in one basket looks like.

In the U.S. we also put all our eggs in one basket, but instead of that basket being a digital certificate/smartcard, it's a nine-digit number that we use as both userid and password.

Except all eggs aren't in one basket - ID card cert usage will be blocked but you can still use Mobile-ID to sign documents, log into govt websites and do everything else that you can do with your ID card.

More like 3 baskets. Estonians can also use a Mobile ID, where private keys, authentication and signature functions are stored on a special SIM card. More recently, an app based Smart ID was also introduced. If you're on one of those services, the certificate revocation doesn't really affect you.

All easy targets for the bear next door - and maybe having a national ID card is not such a good idea in the first place

Not really, I can still use my mobile ID just fine. Not even in a hurry to get my certificates updated.

The vulnerability in question: *The Return of Coppersmith’s A‚ttack: Practical Factorization of Widely Used RSA Moduli∗ https://crocs.fi.muni.cz/_media/public/papers/nemec_roca_ccs...

Estonian ID card uses 2048 byte keys which means generating a private key from a public key takes 140.8 CPU years which is quite fast/trivial/cheap using a distributed approach (botnet, your already existing HW that you use for mining etc).. considering the implications.

>ID Card is compulsory >760,000 ID cards will be blocked >in country of 1.3 million >I have no idea how I can declare monthly VAT numbers It is bad but could be worse. People are signing up for MobileID and there is still possible to update ID cards via going to the office. But poor people abroad. Basically they will be cut off from all the services.

Other nations can watch and learn on Estonia's mistakes. The big question is: can such a scenario (a faulty chip) be completely eliminated?

Clarification: Smart ID does not (yet) have the same functionality as Mobile-ID or ID Card (you can log into some supported services with it but that's about it).

AFAIK they're working on it to get it to the same level so you could give official signatures and log into govt services etc using that as well.

There is only one basket that is made to look that there are three baskets. To get a Mobile-ID need to have an ID-card with valid certificates. If the certs are revoked you can't activate your Mobile-ID. Also you have to pay a monthly fee for Mobil-ID service. Smart-ID requires that you have an ID-Card or Mobile-ID and more importantly it's practically useless as you can't use it for any government services.
