Confidential 5G: seal the core that sees everything on your network

Every subscriber identity, session key and policy decision passes through the 5G core — in memory, in cleartext. enclaive seals core network functions in hardware, with attestation-gated keys.

Kubernetes-native, no changes to core network function code. Selected for the NATO DIANA 2026 cohort.

A 5G network is only as secure as its core

The core must see everything to do its job

What the core actually is

The core is the software-defined control plane behind every 5G network: it authenticates subscribers, manages sessions, routes traffic, enforces policy and holds subscriber data. In modern deployments it runs as containerized network functions on Kubernetes.

+
The structural problem

It cannot authenticate a device without decrypting its identity, or route a session without knowing its keys. All of it exists in memory, in cleartext — and in a conventional deployment, anything that can read the core's memory can read your entire network: a compromised hypervisor, a privileged cloud operator, an insider, or anyone with physical access to the server.

+
Why disk encryption and TLS don't touch it

They protect data at rest and in transit; the core's exposure is data in use.

The threat model

Core-network trust is now a matter of regulation across the EU, and “the vendor promised” no longer passes review. Supplier independence is the thread through all of it — a core whose integrity you can verify is a core whose suppliers you needn't take on faith.

ShowWithout a sealed coreWith enclaive
ThreatWithout a sealed core
Cloud or infrastructure compromise
A hypervisor-level attacker, privileged cloud operator or compromised host reads live core memory: all keys, all sessions.
Insider threat
A privileged admin accesses a running core container; memory and keys are readable.
Supply chain trust
Core functions run on infrastructure whose components you cannot fully vouch for; tampering is undetectable at runtime.
Physical exposure
Portable and remote deployments run on hardware that can be stolen or forensically analyzed; extraction reveals identities, keys and topology.
Sealed core functions, attested keys, standard Kubernetes

Two layers create an end-to-end chain of cryptographic trust: confidential computing seals the core workloads from the infrastructure, and the virtual HSM seals the key material from the core itself — releasing keys only to network functions that prove their integrity.

01
Core functions in encrypted memory

AMF, SMF, UPF, UDM, AUSF, NRF and other containerized network functions run inside hardware trusted execution environments. The CPU encrypts memory during execution — the host OS, hypervisor and hardware owner see nothing readable. No changes to CNF code.

+
02
Subscriber keys in a virtual HSM

Long-term subscriber keys, session master keys and signing certificates live in a software-defined HSM running inside its own sealed environment — HSM-grade custody as a Kubernetes workload, no physical appliance. A network function receives a key only after attestation proves it's running expected, unmodified code.

+
03
Attestation anyone can verify

Operators, regulators and partners can cryptographically verify — in real time — that the core runs genuine, unmodified code in a genuine trusted environment. Trust in the core stops being an assumption and becomes a checkable fact.

+
04
Deployed as a Kubernetes extension

Integrates with SUSE Rancher Prime RKE2, Red Hat OpenShift and other distributions — the orchestration model modern cores already use. A reference deployment with the open-source Open5GS core demonstrates the pattern end to end, including sealed subscriber databases.

One sealed core, four places it runs

The same protection model covers the full spectrum — from hyperscaler-hosted cores to hardware that leaves the building. Running private 5G rather than a network? The short version: your most sensitive box becomes unreadable to everyone who shouldn't read it.

Telco cloud core
Operator cores on cloud infrastructure
+

Host core functions on hyperscalers or European clouds while the cloud operator, its staff and its hypervisor stay outside the sealed boundary — the supply-chain and operator-trust answer regulators increasingly expect from MNOs.

Enterprise private 5G
Campus networks in regulated industries
+

Factories, ports, hospitals and energy grids running private 5G under NIS2 and GDPR get vendor-independent trust verification and sealed subscriber data — evidence included for the audit.

Remote & portable
Deployments where hardware is exposed
+

Offshore platforms, remote industrial sites and portable “5G-in-a-box” units run the core on hardware that can be lost, stolen or seized. Sealed workloads and hardware-bound keys mean extracted equipment yields nothing.

Post-quantum ready, on demand

Traffic recorded today can be decrypted tomorrow — the “harvest now, decrypt later” strategy targets exactly the long-lived secrets a core network carries. An optional PQC module applies NIST-standardized post-quantum algorithms to key exchange and authentication within the core and vHSM stack. Availability is subject to applicable export control regulations.

Built on

A sealed core is what these enforce together — the runtime, the custody and the proof.

FAQ

What network architects ask

Q·01

Does this work with our 5G core vendor?

The protection applies at the runtime layer: containerized network functions run inside sealed environments without code changes, so the model is core-vendor-neutral. The reference deployment runs the open-source Open5GS core end to end; commercial core stacks follow the same pattern. Bring your stack to the first call and we'll map it.

Q·02

What about latency — the UPF is performance-critical.

Memory encryption runs in CPU hardware, so overhead is small for control-plane functions. For the user plane, performance depends on traffic profile and hardware generation. [PLACEHOLDER — insert UPF benchmark figures from engineering before launch.]

+
Q·03

What hardware does an on-prem or portable deployment need?

Servers with current-generation confidential computing support — a selection criterion for private deployments and for vendors building integrated 5G units. In public cloud, the major hyperscalers already offer TEE-capable instances. [PLACEHOLDER — confirm the supported CPU list with product before launch.]

+
Q·04

Which Kubernetes distributions are supported?

The solution deploys as a Kubernetes extension on SUSE Rancher Prime RKE2, Red Hat OpenShift and other standard distributions — not as a separate appliance and not as a replacement for your orchestration choice.

+
Q·05

Can a regulator or partner verify the core independently?

Yes — that's the point of remote attestation. Any authorized party can cryptographically verify, in real time, that the core is running genuine, unmodified code in a genuine trusted environment, instead of relying on contractual assurances.

+
Q·06

We have defense or classified requirements. Where do we start?

In a closed briefing rather than on this page — tactical scenarios, coalition attestation and classified deployment detail are handled there deliberately. Request a briefing and we'll route it to the right team.
