### 07.3 Dual-Layer Cipher Architecture

V131 implements a dual-layer encryption architecture: physical manifold engine for waveform-level anti-spoofing + AES-256-CTR for NIST-compliant cryptographic strength.

| Property | Manifold (Physical) | AES-256-CTR (Digital) | Combined |
|----------|--------------------|-----------------------|----------|
| Effective Strength | ~2^42-2^51 | 2^256 | **2^256** |
| NIST Compliance | No | Yes | **Yes** |
| Latency Overhead | 1.4 ns | 1.6 ns | **1.6 ns** |
| FPGA LUTs | ~1,600 (3.4%) | ~3,400 (7.2%) | **~3,400 (7.2%)** |
| Role | Anti-spoofing | Data confidentiality | **Full coverage** |

### 07.4 Anti-Spoofing: Physical-Layer Zero Trust

| Attack Scenario | BER | False Accepts | Result |
|----------------|-----|---------------|--------|
| Correct key (legitimate) | 0% | N/A | Perfect recovery |
| No key (eavesdrop) | 45.5% | 0 / 10 | Near-random noise |
| Wrong keys (brute-force) | 32% | 0 / 20 | Guessing fails |
| Known plaintext, no key | 43.6% | 0 / 10 | Knowledge insufficient |

**Total: 0 false accepts across 40 attack attempts**

### 07.5 HFT Infrastructure Relevance

- **Zero-Jitter Encryption:** 1.4 ns deterministic latency -- no micro-burst variance. Every packet encrypted at the same cost, every time.
- **Physical Anti-Tamper:** 100% rejection of physical signal injection attacks. Trading data immune to fiber-tap or splice attacks.
- **NIST Dual Defense:** AES-256-CTR provides regulatory audit trail. Manifold engine provides physical-layer resilience.
- **Instant Key Rotation:** Key switch completes in < 66 us with zero downtime. Enables per-session or per-trade key rotation.
