Digital identity management in amateur radio is fragmented and manual, requiring operators to use redundant credentials and insecurely verify their licenses (e.g., via email) across services like remote control and digital voice gateways. This fragmentation impedes security, regulatory compliance, and application development.<br><br>This talk introduces CallSignConnect, a Minimum Viable Federation framework for secure call sign assertion. CallsSignConnect defines an open OAuth 2.0 / OpenID Connect Profile specifically for amateur radio, providing essential claims like callsign and a multi-dimensional assurance vector (IAL, FAL, AAL) aligned with NIST SP 800-63 / ITU-T X.1254.<br><br>The core innovation is its federated model, which utilises ENUM-style DNS delegation (e.g., w.a.1.w.callsign.online) to locate an individual's self-hosted or club-hosted Identity Provider. This federated design minimises reliance on a single central authority and maximises resilience. The talk will address the open-source reference implementation, client libraries, and a strategy for bootstrapping trust by piggybacking on the existing enrolment processes of networks like EchoLink. CallSignConnect offers a path to modern, secure, and standards-based authentication for the global amateur radio service.
