<p class="MsoNormal">EAP Call Notes 26-Apr-18<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Brian Campbell<o:p></o:p></p>
<p class="MsoNormal">Mike Jones<o:p></o:p></p>
<p class="MsoNormal">John Bradley<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A request had come into Mike to update references in http://openid.net/specs/openid-connect-eap-acr-values-1_0.html<o:p></o:p></p>
<p class="MsoNormal"> He will update the WebAuthn reference and add a FIDO2 reference<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A comment on the IETF Token Binding specs came in requesting TLS 1.3 multi-version style negotiation versus 1.2 single-version style<o:p></o:p></p>
<p class="MsoNormal"> John will weigh in as chair saying that the current spec represents considered WG consensus<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">John received a question about whether EAP will enable passing a FIDO attestation to the Connect RP<o:p></o:p></p>
<p class="MsoNormal"> Apparently some people want that<o:p></o:p></p>
<p class="MsoNormal"> It seems like if the RP is trusting the OP, acting on the attestation information is the OP's job<o:p></o:p></p>
<p class="MsoNormal"> Sending the FIDO attestation to the Connect RP could also be a privacy leak<o:p></o:p></p>
<p class="MsoNormal"> A few of us may want to discuss this in Amsterdam<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Brian asked about whether we want additional hash methods for "tbh"<o:p></o:p></p>
<p class="MsoNormal"> John: If we do anything, it should probably be a SHA-3 hash<o:p></o:p></p>
<p class="MsoNormal"> Mike: This is just making an existing secret shorter - not creating a new secret<o:p></o:p></p>
<p class="MsoNormal"> John: The TBID doesn't have any extensible fields and so would be very hard to attack<o:p></o:p></p>
<p class="MsoNormal"> Brian: We could update the metadata to advertise supported hash algorithms<o:p></o:p></p>
