#smartcards — Public Fediverse posts

Hello, wonderful people. Taking a break is good, so I am taking a couple moments to write the #nakeddiefriday post of the week.

Today we have this interesting sample. Yes, it has certainly seen better days; been sitting in a queue for a real while now. This is again a smartcard chip without a name to it. I believe this to be fabbed by Samsung, and be rather old. The chip is built using poly-gate CMOS with 3 metal layers; later processes moved to a higher layer count.

Does anybody know what elementary file 2FE4 contain on SIM cards? It doesn't look like it is described in any standards I've looked at, and its contents varies widely across cards. Maybe boost for reach?

#electronics #smartcards

Hello! It's #nakeddiefriday today, and what I got for you is yet another smartcard chip. Please welcome an unnamed die marked K2D0A, fabbed by STMicro. This came from [REDACTED], used to [REDACTED]. The die oriented with power supply pads on top, so it's possible to figure out which die pads correspond to which module pads. Unusually enough, there are 6 pads bonded out; the function of the extra
pad is not known at this time-- certainly not VPP.

A short thread follows.

Zwei neue Forschungsprojekte der @Cyberagentur starten im Programm SCA4PQC. Sie zielen auf sichere Post-Quanten-Kryptographie – robust gegen physikalische Seitenkanalangriffe. Mit dabei: LEAP-CSP (Cloud & KI) und SPARTAQUS (Smartcards).

#smartcards and #nuitka based project did not play nicely. No clue what went wrong, but I don't have free brain cycles to debug.

I'm looking for a good overview/comparison of different #MFA/#2FA or #PasswordLess authentication protocols.

The recent #Fido2 #MitM risk made me aware that I need to learn more.

As the best way to get an answer on the internet, is to state something wrong, let's try this 😜

#FIDO and FIDO2 are actually a whole set of (related?) protocols.
FIDO includes FIDO #UAF (Universal Authentication Framework) and FIDO #U2F (Universal Second Factor).

FIDO2 is the "successor" of FIDO and consists of two parts.
#WebAuthn and #CTAP (Client to Authenticator Protocol). From the name I would guess that WebAuthn is for web stuff (requiring browser support) and CTAP is for IT infrastructure stuff (???)

#Passkey is based on #Fido2
Other related concepts or protocols are #OTP (one-time passwords), #TOTP (Time-based One-time Password) and #HOTP (“H” in HOTP stands for Hash-based Message Authentication Code (HMAC))

Not sure how #SmartCards play into this.

And not sure which of these methods would work for an offline authentication login into your laptop (and ideally also as key for whole disk encryption)

anyone among my followers familiar with GlobalPlatform 2.3 "Annex A" certificates? Trying to wrap my head around how to reconcile them with X.509 and operate in a system that uses both those and X.509 certificates. #smartcards #followerpower
