Nyx Binary Armor & Firmware Defense Studio — Sovereign Embedded Security

1. VM Bytecode Virtualizer

ACTIVE

Translates sensitive native instructions into a randomized, session-unique custom bytecode executed by an embedded zero-overhead threaded interpreter.

// Native Assembly (IDA/Ghidra Decompiled): 0x1000: mov eax, [ebp-4] 0x1003: add eax, 0x5A879E19 0x1008: xor eax, [ebp-8] 0x100B: ret // Nyx Hardened VM Bytecode (Decompilation Destroyed): [0x00] VOP_LOAD_IMM -> VReg0, 0x5A879E19 [0x07] VOP_ADD_MBA -> VReg0, VReg1 (Dispatcher) [0x0E] VOP_XOR -> VReg0, VReg2 [0x15] VOP_TAMPER_CHK (Canary: 0xDEADBEEF)

2. MBA Polynomial Engine

ACTIVE

Replaces linear arithmetic and boolean logic with high-order non-linear algebraic invariants, eliminating SMT solver simplification.

// Original Expression: let result = x + y; // Transformed High-Order Non-Linear MBA: let term1 = (x ^ y) + 2 * (x & y); let term2 = (x | y) - (x & ~y) + (~x & y); let result = (term1 ^ term2) + 2 * (term1 & term2); // Constant 42 disguised: (A * t + B) * A_inv mod 2^32

3. Silicon PUF Binding

ENROLLED

Binds binary execution to the physical silicon substrate using uninitialized SRAM startup power-on entropy with Hamming syndrome error correction.

                    Hardware Key: 0x8F92_A3C1_B4D2_00E7_99A1
                

4. Inception Anti-Debug Radar

PROTECTED

Continuous inspection of hardware breakpoint registers (DR0-DR7 / DWT), timing cycle jitter (RDTSC), and memory code section hashes.

[STATUS: GREEN] No debugger attached (PEB: Clean) [STATUS: GREEN] DR0-DR7 hardware breakpoint registers: 0x00000000 [STATUS: GREEN] Timing cycle delta: 42 ns (Baseline: Normal) [STATUS: GREEN] .text code integrity: SHA-256 Validated [THREAT ACTION]: Zeroize RAM & Enter ASIL-D Safe Loop

5. AI Tensor Weight Cloaking

ZERO-LEAK

Protects on-device LLM/ONNX weights by streaming encrypted tensor chunks into volatile registers during GEMM multiplication and immediately zeroizing.

// Quantized Llama 3.2 3B Tensor Stream: [Chunk 0x0080] Encrypted Payload (64B) -> Decrypted in L1 Cache [Operation] SIMD Dot-Product with Volatile Activations [Post-GEMM] Instant Zeroization (0xAA -> 0x00 in 0.00 ns) RAM Dump Exposure: 0 Bytes Plaintext

Throughput: 145.8 tok/s Leakage Risk: 0.00%

6. ASIL-D Audit & Delta Log

DETERMINISTIC

Deterministic PRNG seed engine producing bit-for-bit reproducible hardened binaries and cryptographic Delta-Testing verification logs.
