Proximity-Based Secure Data Exfiltration
Enabled reliable transfer of sensitive data from high-risk environments without requiring persistent connectivity or direct operator exposure.
Situation
Operators needed to extract sensitive data from disconnected or monitored environments where persistent communications posed unacceptable operational risk.
Solution
Designed a proximity-based secure data transfer system using short-range encrypted ingestion, store-and-forward routing, and multi-transport backhaul integration.
OUTCOMES
Challenges
Connectivity
- •Intermittent connectivity environments
Transmission
- •Active transmission exposure
Monitoring
- •Upload channels monitored
Solutions
Short-Range Data Ingestion
Edge devices capable of receiving data via short-range interactions (walk-by / drive-by)
- Enabled proximity-triggered transfers
- Avoided persistent transmission signals
- Reduced operator exposure windows
Trusted Agent Authentication
Trusted agent authentication mechanisms.
- Verified authorized transfer participants
- Presided over secure exchange trust
Store-and-Forward Routing
Store-and-forward architecture using encrypted backchannels.
- Buffered transfers securely in transit
- Supported delayed network availability
- Maintained encrypted routing continuity
Multi-Transport Backbone Integration
Existing multi-transport backbone (cellular, satellite, radio)
- Leveraged resilient transport redundancy
- Ensured eventual delivery reliability
- Enabled global transfer reach
End-to-End Secure Routing
End-to-end encrypted routing to centralized secure endpoints.
- Preserved confidentiality throughout transit
- Eliminated intermediate exposure risks
- Maintained chain-of-custody assurance
