Elevated assurance for the highest-stakes deployments
The far end of the same protocol. For government and critical infrastructure, the question is not whether the cryptography is strong, it is how rigorously the hardware is validated and how aggressively it resists physical attack. reco3 and reco4 raise that envelope.
Assurance as a requirement
Critical infrastructure and sensitive government deployments operate under requirements where independent validation and physical tamper protection are not preferences, they are conditions of use. Sovereignty over keys and data, and confidence against a capable adversary, are part of the baseline.
These environments still benefit from everything TAWK already provides: resilient, infrastructure-independent operation and a post-quantum core. What they add is a hardened, validated coordinator and, at the top end, hardware that actively defends itself.
What this configuration brings
Higher validation, same protocol
reco3 targets a FIPS 140-3 Level 3 class of validation, with physical and identity protections beyond reco2. The protocol does not change; the assurance envelope does.
Tamper-active at the top end
reco4 targets the most stringent class (FIPS 140-3 Level 4), where hardware actively responds to physical attack. A deliberately niche but real segment.
Sovereign and auditable
Identity-bound trust and an openly specified protocol support deployments that need to own their keys and verify what they are running.
One substrate, many tiers
A single protocol spans consumer to maximum-assurance, so investment and integration carry across the whole range rather than fragmenting.
What it looks like
A critical-infrastructure operator runs a resilient command channel that survives loss of commercial networks.
Validated, hardened coordinators anchor trust for a sensitive deployment.
Tamper-active hardware protects the most sensitive nodes against physical compromise.
An agency verifies and governs its own deployment on an open, auditable protocol.
