Air-Gapped Audit Bundle Exchange
Portable, self-contained evidence bundles for environments where network connectivity is unavailable, restricted, or untrusted. Complete cryptographic verification without external dependencies.
Target System.
Disconnected, Denied, Intermittent, or Limited (DDIL) environments including classified networks, forward-deployed military systems, critical infrastructure with network isolation, and regulated environments requiring air-gapped audit trails.
Threat Model.
- Tampered evidence during network transit
- Unauthorized modification of audit records
- Replay attacks with stale evidence
- Verifier substitution attacks
- Chain discontinuity exploitation
Integration Points.
