Trinity Shield™

Layer 8 of the Mathematical Defense Layer (MDL) for Trinity Protocol

"Mathematically Proven. Hardware Protected."

Overview

Trinity Shield™ is a production-ready Rust implementation of hardware-isolated security for multi-chain consensus validators. It provides three integrated defense layers running inside Intel SGX/AMD SEV trusted execution environments.

Features

Perimeter Shield

• Rate Limiting: Token bucket algorithm with per-source tracking
• DDoS Protection: Circuit breaker pattern with exponential backoff
• IP Filtering: Allowlist/blocklist with CIDR support
• Request Validation: Size limits, injection detection, format validation

Application Shield

• Multi-Chain Authentication: Ed25519 (Solana), Secp256k1 (Arbitrum), Dilithium5 (TON)
• Role-Based Authorization: Capability tokens with expiry
• Session Management: Secure session handling with timeouts
• Input Validation: Schema validation, address format checking

Data Shield

• Encryption: AES-256-GCM and ChaCha20-Poly1305
• Key Sealing: Hardware-bound keys (MRENCLAVE/MRSIGNER policy)
• Integrity: Merkle proofs and HMAC verification
• Key Management: Rotation, wrapping, and hierarchical derivation

Consensus Engine

• 2-of-3 Voting: Byzantine fault-tolerant consensus
• Lean-Proven Rules: Operations validated against formal proofs
• Multi-Chain: Arbitrum (security), Solana (monitoring), TON (recovery)
• Replay Protection: Nonce tracking and operation timeouts

Attestation Service

• Remote Attestation: SGX quote generation and verification
• DCAP Support: Local verification without Intel dependency
• Quote Caching: Automatic refresh before expiry

Building

Standard Build

cargo build --release

SGX Enclave Build

cargo build --release --features sgx --target x86_64-fortanix-unknown-sgx

Simulation Mode (for testing)

cargo build --release --features simulation

Usage

use trinity_shield::{TrinityShield, ShieldConfig, ChainId};

// Create shield for Arbitrum validator
let config = ShieldConfig::for_chain(ChainId::Arbitrum);
let shield = TrinityShield::new(config)?;

// Process incoming request
let validated = shield.process_request(&request_bytes, &source)?;

// Sign a consensus vote
let signed_vote = shield.sign_vote(&operation)?;

// Generate attestation for on-chain verification
let attestation = shield.generate_attestation()?;

Security Model

Trinity Shield operates on a zero-trust model:

1. Defense in Depth: Three independent security layers
2. Hardware Isolation: Keys sealed to SGX enclave
3. Fail-Secure: All failures default to rejection
4. Audit Trail: All operations logged (without sensitive data)
5. Quantum Resistance: TON chain uses ML-KEM-1024 and Dilithium-5

Lean Proof Integration

Trinity Shield's consensus rules are formally verified using Lean 4:

• 58 of 78 theorems proven (74% complete)
• Operation validation rules match Lean specifications
• Continuous verification in CI pipeline

See TRINITY_SHIELD_LEAN_INTEGRATION.md for details.

Benchmarks

Run benchmarks:

cargo bench --features std

Expected performance on modern hardware:

• SHA-256 (1KB): ~150 MB/s
• AES-256-GCM (1KB): ~1 GB/s (with AES-NI)
• Rate limiter check: ~5M ops/sec
• Signature verification: ~15K ops/sec

Testing

# Unit tests
cargo test

# With coverage
cargo tarpaulin --out Html
