Public Review Period for Two Proposed EAP Implementer’s Drafts

Published April 22, 2019
The OpenID Enhanced Authentication Profile (EAP) Working Group recommends approval of the following specifications as OpenID Implementer’s Drafts: The first specification enables OpenID Connect implementations to apply Token Binding to the OpenID Connect ID Token. This use of Token Binding protects the authentication flow from man-in-the-middle and token export and replay attacks. The second specification enables OpenID Connect Relying Parties to request that specific authentication context classes be applied to authentications performed; specifically, an authentication context class reference value is defined that requests that phishing-resistant authentication be performed and another is defined that requests that phishing-resistant authentication with a hardware-protected key be performed. These policies can be satisfied, for instance, by using W3C Web Authentication (WebAuthn) or FIDO authenticators. An Implementer’s Draft is a stable version of a specification providing intellectual property protections to implementers of the specification. This note starts the 45-day public review period for the specification drafts in accordance with the OpenID Foundation IPR policies and procedures. Unless issues are identified during the review that the working group believes must be addressed by revising the drafts, this review period will be followed by a seven-day voting period during which OpenID Foundation members will vote on whether to approve these drafts as OpenID Implementer’s Drafts. For the convenience of members, voting will actually begin a week before the start of the official voting period. The relevant dates are:
  • Implementer’s Drafts public review period: Monday, April 22, 2019 to Thursday, June 6, 2019 (45 days)
  • Implementer’s Drafts vote announcement: Friday, May 24, 2019
  • Implementer’s Drafts voting period: Friday, June 7, 2019 to Friday, June 14, 2019 (7 days)*
* Note: Early voting before the start of the formal voting will be allowed.
