01
Cross-slice breach risk
Shared infrastructure means a key compromise in one slice can expose others if isolation isn't enforced cryptographically, not just logically.
What makes slice security hard
Multi-tenant 5G infrastructure creates cryptographic problems traditional HSMs weren't built for.
02
Multi-country key sovereignty
Operators running across borders need key residency and control that matches each jurisdiction's requirements.
03
HSM scale limitations
Hardware HSMs don't scale cleanly to the number of slices, tenants and regions a modern 5G core needs.
04
NIS2 and critical-infrastructure obligations
Telecom operators fall under NIS2 as critical infrastructure, with real reporting and resilience obligations.
Per-slice keys, distributed by MPC
Each network slice gets its own key, generated and operated through DuoKey's MPC KMS. The key is never assembled in one place, cryptographic operations happen across distributed nodes, so compromising one node or one slice does not expose another.
Per-slice isolation: enterprise, MVNO, IoT and consumer slices each hold an independent key
Instant slice revocation: cut off a compromised slice's key without touching any other tenant
No hardware HSM required: software-defined MPC nodes replace HSM appliances at the core and edge
Key Benefits
Why telcos move slice key management to MPC
Per-slice cryptographic isolation
No slice shares a key with another, a breach in one tenant's slice stays contained to that slice.
Instant revocation, no fleet-wide rotation
Revoke a single slice's key shares the moment a compromise is detected, without rotating every other slice.
Sovereign, multi-country deployment
Run MPC nodes in the jurisdictions your regulators and customers require, without depending on hardware shipped to every site.
Lower cost and complexity than HSM
Software-defined key management removes the hardware procurement, key ceremonies and per-site HSM footprint.
