- progbits 8mo agoRevocation lists can be distributed.

- lxgr 8mo agoYes, but they still originate somewhere, and if that source goes offline, you're still at risk of accepting stolen credentials.
- VorpalWay 8mo agoYes, but under the assumption that downtime is typically short (a few hours), that small risk seems better than a foreign nation state actor being able to block essential services like identifying with healthcare, or sending transactions.
- jdmoreira 8mo agoSure... but it should degrade to work when the central services are down. You should still be able to authenticate with each individual service when the centralised service is down. There is no reason why you shouldn't be able to login to your bank under these circumstances.
- Ekaros 8mo agoFinnish system works like that. If central system is down I can still log in to bank. But I can not log into say tax or healthcare system.
- j16sdiz 8mo agoI don't understand. We don't have real time revocation for passports, do we? In fact, we don't have real time revocation of any document until very recently...
- zirror 8mo agodon't we? We call somewhere and revoke the Passport, atleast in Germany.
- lxgr 8mo agoBut does that propagate to every entity worldwide using passports for identification, including all non-government-affiliated companies and KYC providers?
- Muromec 8mo agoThat's very true for a lot of PKI systems too. The revocation lists are published, but nobody is reading them.
- lxgr 8mo agoAt least they exist. I've tried looking into this in the past, and I haven't really found any public passport revocation list, even of just numbers (i.e. without disclosing associated names or any other sensitive data).
- xorcist 8mo agoWe do. There are centralized databases of passport serial number, for blacklisting (revocation) or just persons of interest.
- lxgr 8mo agoFor all countries? I was always wondering about that when doing one of these wonderful "take a selfie of you holding your passport" "authentication" procedures...
