Few open questions around FIDO2 webauthn and U2F

Resolving broken source in Maven central repository

FIDO2 compatibility with U2F/CTAP1

QUESTION

Few open questions around FIDO2 webauthn and U2F

Asked 2020-Jun-25 at 12:29

I've read in multiple places that since U2F doesn’t have a concept of a user it can be used as one of the factors for login (in MFA) but not ideal for passwordless whereas webauthn has the concept of users which could help with passwordless. My question is what is that extra that webauthn adds to allow this? Yes, we do pass user information when we create the credentials but in the end we're returned a credential id (which seems to be very similar to the keyhandle) and is used to associate the user (on the server). For what i understand, webauthn def has the advantage of working with different authenticators (not just U2F keys) but apart from that what exactly does webauthn add to make passwordless easier.
CTAP describes how the browser and operating system establish communications with a compliant authentication device over USB, NFC or BLE communication mediums. Could we say CTAP is an application layer protocol (like FTP?)
When i use the finger print feature on my android phone to verify using webauthn, is the browser communicating with the OS (which in turn pops up the authenticator) using CTAP2? Where does ufc, nfc, ble, internal come up here?
Here is a diagram for browser support for webauthn. In chrome/android, what does it mean to have stable support for WebAuthnAPI but In development support for CTAP2? Does it mean some authenticators wont be supported?

The spec specifically refers to it as an application layer protocol in the abstract:

https://fidoalliance.org/specs/fido-v2.0-ps-20190130/fido-client-to-authenticator-protocol-v2.0-ps-20190130.html

The implementation from browser to browser and OS to OS will differ. Windows 10 now offers a native API which sits over the top of Windows Hello and standardises interactions with authenticator devices. Prior to this browsers on Windows had their own implementations and their own UIs. A given CTAP2 implementation would include support for 1 or more of the transports defined in the spec, each having a binding specific to the needs of that transport. The spec is worth a read.

Lack of CTAP2 support in the examples given above would mean that while you could use a backwards compatible FIDO2/CTAP2 compliant device you'd miss out on the added features of FIDO2 - primarily resident keys and thus the ability to have passwordless logins.

ETA: This artical is pretty good and has some nice diagrams: https://hybrismart.com/2019/05/23/authentication-with-hardware-security-keys-via-webauthn-in-sap-commerce-cloud/

QUESTION

FIDO2 compatibility with U2F/CTAP1

Asked 2020-Mar-14 at 19:14

There are many sources that say FIDO2/CTAP2 is backward compatible with U2F:

...all previously certified FIDO U2F Security Keys and YubiKeys will continue to work as a second-factor authentication login experience with web browsers and online services supporting WebAuthn. - Yubico

But after looking at the specifications, I'm having trouble seeing how that actually works in practice. Specifically, it seems like there is a mismatch between FIDO2's relying party identifier and U2F's application identity.

In U2F, the application identity is a URL, like https://example.com. SHA-256 of the application identity is called the application parameter. The application parameter is what is actually sent to the authenticator during registration and authentication.

In FIDO2, the equivalent seems to be the relying party identifier, which is defined to be a domain name, like example.com.

The relying party identifier and the application identity serve the same purpose in both FIDO2/CTAP2 and U2F. However, CTAP2 authenticators get the relying party identifier directly as an UTF8 string, whereas U2F authenticators only get a SHA-256 hash of the application identity (the application parameter).

The FIDO documentation for CTAP describes how CTAP2 maps onto CTAP1/U2F. In it, they simply treat the relying party identifier directly as the application identity:

Let rpIdHash be a byte array of size 32 initialized with SHA-256 hash of rp.id parameter as CTAP1/U2F application parameter (32 bytes)

This seems inconsistent. Let's say I were example.com, and I adopted U2F second-factor authentication early on. My application id would be https://example.com, so my original U2F application parameter would be SHA256("https://example.com"):

WebAuthn supports backward compatibility with U2F via the AppID Extension documented in the W3C WebAuthn spec. The Relying Party (RP) passes the U2F application identity to the browser via this extension.

Here are a few RP AppID examples in Python and Java.

Install ctap

Clone the GitHub repository to your machine using. NOTE 1: you can clone wherever you like, but on Unix-based systems we recommend to clone in the home directory, to be compatible with the CTAP code generation tool. NOTE 2: we have used git LFS to track/manage large data files (in *.mat and *.set format). This implies that you need to set up LFS by. Unless you want to ignore the data files (which will prevent some example scripts from running); then it is sufficient to clone without LFS installed (for more LFS options see here). Add directory trees <dst_dir>/ctap/ and <dst_dir>/dependencies/ to your Matlab path, including subdirectories. One option to accomplish this is to set the Matlab working directory to the CTAP root directory <destination dir>, and then run ctap_set_path.m to configure Matlab path. You need to have EEGLAB added to your Matlab path (instructions here). ctap_set_path.m can also accomplish this, if you edit to match the setup on your machine and run. To have your preferred path configuration loaded every time Matlab starts, edit your startup.m script by copying the contents of ctap_set_path.m. See ([Matlab's instructions here] (https://www.mathworks.com/help/matlab/ref/startup.html)) regarding the startup.m script.
A minimalistic working example can be found in ~/ctap/templates/minimalistic_example/. Try running script. If the seed data packaged with CTAP was found (i.e. the Matlab path was correctly configured), then runctap_minimal should read seed data, create synthetic data and run an example CTAP pipe on the synthetic data. Results are stored under fullfile(cd(), 'example-project'). To start your own pipe, copy the cfg_minimal.m and runctap_minimal.m files and use them as a starting point. Note: runctap_minimal.m takes as input a small dataset included under ~/ctap/data/, which it uses to generate synthetic data and illustrate several preprocessing steps. To have it find the data, set the Matlab current directory to the root of the CTAP repo you have just cloned, i.e. <destination dir>. You can also set the output directory in runctap_minimal.m. More examples are available under ~/ctap/templates/. General documentation can be found in the CTAP wiki pages.
