Test Plan: Packet Transfer Integrity
Secure Packet Transfer Integrity Stack v0.1
This is a conceptual and toy-test plan. It is not a production security validation plan.
Test 1: Clean verified transfer
Input: Known payload, known source hash, valid authenticated session, destination hash match.
Expected state: GREEN
Reason: Payload, identity, session, boundary, and audit checks pass.
Test 2: Hash mismatch
Input: Known payload altered before or after transfer.
Expected state: RED
Reason: Payload fidelity fails.
Test 3: Packet loss / retransmission spike
Input: Transfer with packet loss or jitter, but final payload hash and session checks pass.
Expected state: YELLOW or GREEN depending on threshold.
Reason: Transport degradation occurred; final fidelity may still pass.
Test 4: Replay attempt
Input: Replayed packet/session message from prior valid transfer.
Expected state: RED if replay signal is detected or anti-replay protection fails.
Reason: Boundary and handshake integrity fail.
Test 5: Downgrade attempt
Input: Negotiated security is weakened or fallback is forced.
Expected state: RED unless explicitly authorized and logged.
Reason: Boundary-preserving transfer and handshake integrity are under hard-fault pressure.
Test 6: Stale or invalid certificate
Input: Certificate expired, mismatched, revoked, unknown, or policy-invalid.
Expected state: YELLOW or RED depending on policy.
Reason: Authentication gate is degraded or failed.
Test 7: Metadata concern
Input: Payload is protected, but routing, timing, endpoint, or metadata exposure exceeds the declared boundary.
Expected state: YELLOW or RED depending on boundary sensitivity.
Reason: R_boundary is degraded even if H_payload passes.
Test 8: Audit-chain discontinuity
Input: Source/destination hashes exist, but transfer logs or provenance chain is missing, discontinuous, or unverifiable.
Expected state: RED or downgraded claim state.
Reason: Evidence boundary no longer supports full verification.
Non-claim
Passing these toy tests does not establish production security, formal proof, cryptographic soundness, or adversarial robustness.
