What's driving the conversation

Why this sector is rethinking cloud now.

Compelled disclosure under foreign law

Defence data on US-controlled clouds is reachable by US legal process. Coalition data on US-controlled clouds is reachable by US legal process. The entire premise of sovereign defence storage requires architectural enforcement.

Post-quantum migration mandate

Both Canada's Cyber Centre PQC guidance and the NSA CNSA 2.0 profile call out KEM and signature halves separately. SkyeConnex ships both — ML-KEM-1024 and ML-DSA-87 — in production today.

Air-gap and disconnected operations

Field deployments need reliability primitives — resumable chunked upload, async scatter, mobile resume across battery cycles — that hyperscaler clients don't ship.

How it lands

What SkyeConnex actually does here.

  1. USE 01

    Shamir M-of-N custodian quorum

    Split-Authority Decryption requires multiple custodians to unlock the most sensitive scopes. No single insider can compel access.

  2. USE 02

    Air-gap deployment

    The same code that runs app.skyeconnex.com runs in a customer's own VPC, on-prem, or air-gapped. Provider plugin SDK lets you bring sovereign storage in fewer than 500 lines.

  3. USE 03

    Field reliability

    Mobile clients persist in-flight upload_ids to local storage. An OS-killed app or backgrounded session resumes on next launch. Field upload survives a dead battery.

Regulatory deep-dive for military & defence

CCCS PQC migration guidance

The Canadian Centre for Cyber Security publishes guidance on the post-quantum migration. The 2025 update emphasises that both key-encapsulation and signature algorithms must migrate independently — and that hybrid constructions are recommended during the transition window. SkyeConnex ships ML-KEM-1024 (FIPS 203) hybrid wrap and ML-DSA-87 (FIPS 204) signatures in production today on the Sovereign tier.

NSA CNSA 2.0

The NSA's Commercial National Security Algorithm Suite version 2.0 specifies the post-quantum primitives required for protecting National Security Systems. ML-KEM and ML-DSA are both named explicitly. SkyeConnex's defence-grade configuration aligns with CNSA 2.0 — making the architecture suitable for coalition defence workloads where cross-border interoperability matters.

DGSI 100-8 Sovereign / Defence tier

The Standards Council of Canada's draft sovereign-cloud standard defines a Sovereign / Defence tier with the most stringent requirements: split-authority decryption, jurisdiction-locked shards, mandatory PQ-hybrid wrap, dual-signed audit log, optional air-gap deployment. SkyeConnex's defence configuration satisfies all of these.

What good looks like

For organisations in military & defence that are serious about sovereignty, the architectural baseline includes:

  • Shamir M-of-N custodian quorum for unlocking the most sensitive scopes (no single insider can compel access).
  • Post-quantum hybrid key wrap (ML-KEM-1024 + AES Key Wrap) so harvest-now-decrypt-later attacks fail.
  • Post-quantum signatures (ML-DSA-87) on every audit-log entry, offline-verifiable.
  • Jurisdiction-locked shards: data physically restricted to nominated countries by policy.
  • Optional fully air-gapped deployment with no platform telemetry leaving the customer network.
  • Field-grade reliability primitives: resumable chunked upload, async scatter, mobile resume across battery cycles.

SkyeConnex delivers all of the above by default — see the architecture and the cryptographic posture.

FAQ

Common questions in military & defence

Is SkyeConnex suitable for classified workloads?

On the Sovereign tier with Split-Authority Decryption configured and air-gap deployment, SkyeConnex is architecturally suitable for classified-handling. Final accreditation depends on the customer's own evaluation programme — we provide architecture documentation aligned with DGSI 100-8 Sovereign / Defence tier requirements.

How does Split-Authority Decryption work in practice?

Shamir Secret Sharing splits the decryption secret among M-of-N custodians. To unlock the most sensitive scopes, M custodians must independently authorise the unwrap. No single custodian can compel access — including the customer's own administrators.

Can SkyeConnex run in a fully air-gapped environment?

Yes. The platform code, including SkyeGXU on-prem AI, runs without network access to app.skyeconnex.com. License verification falls back to a 24-hour grace period in absence of connectivity, and an offline licence-renewal flow handles longer disconnections.

Does SkyeConnex support coalition / cross-jurisdictional defence operations?

Yes. Allow-list policy can be configured to admit Five Eyes jurisdictions while blocking others. Per-file evidence of residency makes coalition data-sharing arrangements auditable. CNSA 2.0 alignment ensures interoperability with US National Security Systems.
