Is Identity federation PQC Quantum Proof? Cyber Program & PQC
Verdict
Identity federation PQC planning is a multi-party migration: your IdP, partner IdPs, and every relying party. Start metadata inventory and dual-stack signing plans early.
Overview
M&A, campuses, and SaaS create webs of trust. Algorithm changes need coordination windows similar to large cert rollovers.
Program inventory focus: Federation multiplies relying parties that must accept new algorithms. Typical classical surfaces: Cross-domain SAML/OIDC; Brokered trust. Cross-read /security/program and /assessment. Educational only—not compliance advice.
