Utilities are expanding connected infrastructure faster than traditional key management can support - creating gaps across manufacturing, deployment, and lifecycle operations. Protect millions of smart meters with enterprise-grade key lifecycle management.
Nexus IoT KMS closes that gap. The solution delivers complete cryptographic key control for Advanced Metering Infrastructure (AMI), ensuring security, compliance, and operational efficiency across your utility network.
What you gain
- End‑to‑end key lifecycle control (generation → retirement)
- HSM‑backed, vendor‑agnostic architecture
- Built for large‑scale AMI environments

Smart Meter Security Challenges
AMI security is not a device problem - it’s a lifecycle problem. Connected smart meter infrastructure brings benefits—and security risks. Address them with enterprise KMS.
Securing individual smart meters, data concentration units (DCUs), head-end systems (HES), and the meter data management (MDM) system communications
Meeting IEC 62056 standards, including DLMS/COSEM security suites 0, 1, and 2 for standardized metering protocols
Securing wide area networks (WAN), home area networks (HAN), and local metrological networks (LMN) with proper key distribution
Managing authorized access for administrators, technicians, and service personnel using hand-held units (HHU)
Meeting current and future security regulations while maintaining audit trails and compliance documentation
Managing millions of meter keys across production, deployment, rotation, and retirement at scale
Complete Key Lifecycle Management
Most vulnerabilities occur between lifecycle stages, not within them. From meter production through retirement, Nexus IoT KMS automates and secures every phase.
Generation
Certified entropy key creation with HSM protection
Injection
Secure meter production key embedding
Distribution
AMI component provisioning and activation
Active Use
Continuous monitoring and access control
Rotation
Scheduled updates preventing expiration
Retirement
Secure archival and decommissioning
