Cisco Live US 2025 (San Diego) digest Program Core pick San Diego · 8–12 June 2025

Abstract

Stefan Duernberger (Cisco)

  • Why: Directly the identity stack the PM tracks — passkeys, OAuth 2.0/OIDC — plus two genuinely emerging items (Google's Device-Bound Session Credentials and Shared Signals and Events) that sit beyond the basics.
  • What: The role and implementation of passkeys, OAuth 2.0 and OIDC for cross-platform authentication, Google DBSC, Cisco Duo Passport, and an overview of Shared Signals and Events — all framed within a Zero Trust architecture (from abstract only).
  • How: Protocol survey connecting credential technology (passkeys/WebAuthn) to authorization frameworks (OAuth/OIDC) to session-integrity (DBSC) and continuous-signal (SSSE) mechanisms.
  • Where applicable: General web and enterprise authentication; the Duo Passport portion is Cisco product content, but the protocol material is standards-based and general.
