This article explains why digital certificates are critical to 5G security, arguing that certificate-based authentication and encryption must be applied broadly across RAN, core, transport and service layers to secure slice-based services and APIs; it also discusses certificate authority deployment options (single vs multiple CAs and logical/physical separation) and urges communications service providers and digital service providers to plan certificate management as part of 5G architecture.
