Post-Quantum Enhancements to TLS-Based EAP Methods

This document proposes enhancements to TLS-based EAP methods, including the Extensible Authentication Protocol with Transport Layer Security (EAP-TLS), EAP Tunneled TLS (EAP-TTLS), Protected EAP (PEAP), and EAP Tunnel Method (TEAP), to incorporate post-quantum cryptographic mechanisms. It also addresses challenges related to large certificate sizes and long certificate chains, as identified in [RFC9191], and provides recommendations for integrating PQC algorithms into TLS-based EAP deployments.
