ZKP Assurance for
Coalition ISR Fusion

A five-layer zero-knowledge proof protocol enabling coalition partners to share sensor track data while preserving operational security and preventing data incest and replay attacks.

SAFE Protocol — 5-Layer Architecture

L1

Verifiable Fidelity

ZKP proves sensor tier without raw measurements

L2

Anonymous Lineage

Bloom filter detects incest loops, preserves sensor anonymity

L3

Physics-Based Identity

Target ID proofs bound to kinematic plausibility

L4

Freshness Binding

Timestamp proofs prevent replay beyond 30s window

L5

Recipient Binding

Hash-bound fields restrict sensitive data to authorized nodes

Coalition Threat Model

🎯

External Adversary

Injects replay tracks and forged sensor data into the data link

⚠️

Compromised Partner

Coalition node sends malformed ZK proofs or inflated quality claims

👁

Curious Observer

Unauthorized node attempts to infer classified target identity from kinematics
