xSlice: 5G Network Slice Isolation

The Problem

5G network slicing creates logically isolated networks on shared infrastructure, but current isolation relies on software boundaries that can be bypassed.

A compromised RAN or core network node can access data from multiple network slices simultaneously. Software-defined isolation is only as strong as the hypervisor or orchestrator enforcing it.

Critical infrastructure slices (healthcare, defense, utilities) share physical resources with consumer traffic. A single breach can cross slice boundaries.

The Old Way

The PRIVATE.ME Solution

xSlice uses XorIDA to split control and user plane data across independent physical channels via Xshield. Even if one channel is compromised, zero information about the slice is revealed.

Each network slice’s data is XorIDA-split at the point of origin and routed via Xshield multi-channel delivery across independent network paths. Reconstruction requires K-of-N shares from different physical channels.

DID identity authenticates every network element. Slice-to-slice isolation is cryptographically enforced, not just policy-defined. HMAC integrity verification detects any channel compromise.

The New Way

How It Works

xSlice combines Xshield multi-channel routing with XorIDA split-plane isolation and DID-authenticated network elements.

Use Cases

Integration

import { SliceGuard } from '@private.me/slicesplit';

const guard = await SliceGuard.create({
  sliceId: 'healthcare-iot',
  channels: [pathA, pathB, pathC],
  threshold: { k: 2, n: 3 }
});

Security Properties

Verifiable Data Protection

Every operation in this ACI produces a verifiable audit trail via xProve. HMAC-chained integrity proofs let auditors confirm that data was split, stored, and reconstructed correctly — without accessing the data itself.

Ship Proofs, Not Source

xSlice generates cryptographic proofs of correct execution without exposing proprietary algorithms. Verify integrity using zero-knowledge proofs — no source code required.
