Certificate and Key Management for Telecom Operators and 5G Networks
Automate certificate lifecycle across 5G core, RAN, and transport networks. Secure SIM/eSIM provisioning, NFV infrastructure, and network function signing. Built for 3GPP, GSMA, NESAS, and ETSI NFV compliance.
Why Telecom Operators Struggle with Certificate and Key Management
5G core network certificate volumes exceed manual management capacity
5G Service-Based Architecture (SBA) relies on TLS for inter-network-function communication per 3GPP TS 33.501. Each Network Function (NF) — AMF, SMF, UPF, NRF, NSSF — requires its own certificate for mutual TLS authentication. A single 5G core deployment can generate thousands of certificates across network slices, and operators managing multi-vendor, multi-site cores face certificate sprawl that manual processes cannot track.
SIM and eSIM provisioning security requires end-to-end key management
GSMA SGP.22 and SGP.32 specifications for eSIM remote provisioning depend on a chain of certificates from the Certificate Issuer (CI) through SM-DP+ and SM-DS servers. Compromised provisioning keys can enable SIM cloning or unauthorized profile downloads. Operators managing millions of eSIM profiles need automated key rotation and certificate lifecycle management across their provisioning infrastructure.
NFV infrastructure certificates span multiple virtualization layers
ETSI NFV architecture introduces certificates at the VIM, VNFM, NFVO, and individual VNF layers. Each layer has its own certificate requirements for API authentication, inter-component TLS, and management plane security. Operators running multi-vendor NFV stacks — VMware, Red Hat, Wind River — face fragmented certificate management across orchestration layers with no unified visibility.
RAN equipment identity and O-RAN security add new certificate requirements
Open RAN architectures per O-RAN Alliance specifications introduce new certificate requirements for RAN Intelligent Controllers (RIC), O-CU, O-DU, and O-RU components. Each RAN element requires device identity certificates for mutual authentication, and the disaggregated architecture means certificates must be managed across equipment from multiple vendors with different provisioning interfaces.
How QCecuring Solves Certificate and Key Challenges in Telecom
Automated certificate lifecycle for 5G core network functions
Discover and manage TLS certificates across all 5G SBA network functions including AMF, SMF, UPF, NRF, and NSSF. Automate certificate enrollment, renewal, and revocation per 3GPP TS 33.501 requirements. Track certificate inventory per network slice, per site, and per vendor with centralized policy enforcement.
SSL/TLS Certificate Lifecycle ManagementNFV and O-RAN certificate governance
Manage certificates across ETSI NFV orchestration layers and O-RAN disaggregated components. Enforce certificate policies covering key strength, algorithm compliance, and validity periods across multi-vendor infrastructure. Generate audit reports mapping certificate inventory to NESAS security assurance requirements.
SSL/TLS Certificate Lifecycle ManagementSSH key management for telecom network operations
Discover and govern SSH keys across network management systems, OSS/BSS platforms, and NOC infrastructure. Enforce key rotation schedules for network engineers and vendor support teams, remove orphaned keys from departed personnel, and implement just-in-time access for critical network element management.
SSH Key Lifecycle ManagementPrivileged access control for network element management
Implement SSH access governance for engineers managing routers, switches, BNG, and core network elements. Enforce approval workflows for privileged operations, log all session activity, and map access grants to specific change tickets for audit compliance and incident investigation.
SSH Key Lifecycle ManagementNetwork function and firmware signing for telecom software supply chain
Sign VNF packages, CNF container images, RAN firmware, and network element software updates with centrally managed signing keys. Enforce signing policies per network function type and deployment environment. Maintain audit trails for NESAS and 3GPP SCAS (Security Assurance Specification) compliance evidence.
Code SigningUse Cases in Telecom and 5G
5G core certificate automation for multi-vendor deployment
A Tier 1 operator deploying 5G SA core across 3 vendors and 12 sites automates certificate lifecycle for 8,000+ network function certificates. Automated discovery identifies certificates across all network slices, and renewal workflows eliminate the manual coordination that previously caused certificate-related signaling failures during peak traffic.
eSIM provisioning infrastructure security
A mobile operator managing 20 million eSIM profiles automates certificate management across its SM-DP+, SM-DS, and CI infrastructure. Key rotation for provisioning servers is automated on GSMA-recommended schedules, and certificate chain validation ensures end-to-end integrity of profile download operations.
O-RAN equipment certificate management
An operator deploying O-RAN across 500 cell sites manages device identity certificates for multi-vendor RIC, O-CU, O-DU, and O-RU components. Centralized certificate provisioning replaces per-vendor manual enrollment, reducing site commissioning time and ensuring consistent mutual authentication across the disaggregated RAN.
VNF package signing for NFV marketplace
A network equipment provider signs all VNF packages distributed to operator customers with centrally managed keys. Operators verify package signatures before onboarding VNFs into their NFVO, establishing a trusted software supply chain that meets NESAS security assurance requirements.
