AEGIS Post-Quantum Cryptography for BlockchainVM Targets (Substrate, CosmWasm, EVM, Move)

# @synergy-network/aegis-pqvm

**AEGIS Post-Quantum Cryptography for Blockchain/VM Targets**

Complete implementation framework for integrating NIST-selected post-quantum cryptography into blockchain platforms, smart contract runtimes, and virtual machines.

## 🚀 Overview

The `aegis-pqvm` package provides production-ready Post-Quantum Cryptography (PQC) implementations specifically designed for blockchain ecosystems. It enables quantum-resistant cryptography across multiple blockchain platforms while maintaining compatibility with existing smart contract environments.

## 📦 Installation

```bash
# For blockchain development
npm install @synergy-network/aegis-pqvm

# Or install from source
git clone https://github.com/synergy-network-hq/aegis.git
cd aegis/pqc/pqvm
cargo build --release
```

## 🏗️ Supported Blockchain Platforms

### 1. **Substrate (Polkadot/Kusama)**
```rust
// In your Substrate runtime
use aegis_pqvm::substrate::pallet;

impl<T: Config> Pallet<T> {
    pub fn quantum_resistant_keygen() -> Result<([u8; 1632], [u8; 800]), &'static str> {
        PqcInterface::mlkem_keygen("mlkem512")
    }
}
```

### 2. **Ethereum Virtual Machine (EVM) Precompiles**
```solidity
// Precompile addresses (0x10 - 0x19)
contract QuantumResistantContract {
    // ML-KEM-512 key generation (precompile 0x10)
    function generateMLKEM512Keys() public returns (bytes memory pk, bytes memory sk) {
        (bool success, bytes memory result) = address(0x10).call(
            abi.encodePacked(uint8(0)) // keygen operation
        );
        require(success, "Precompile call failed");
        // Parse result: pk (800 bytes) + sk (1632 bytes)
    }
}
```

### 3. **CosmWasm Smart Contracts**
```rust
// In your CosmWasm contract
use cosmwasm_std::{Binary, Deps, DepsMut, Env, MessageInfo, Response, StdResult};

pub fn instantiate(
    deps: DepsMut,
    env: Env,
    info: MessageInfo,
    msg: InstantiateMsg,
) -> StdResult<Response> {
    // Generate quantum-resistant keypair
    let (pk, sk) = pqc.mlkem_keygen("mlkem768")?;
    Ok(Response::default())
}
```

### 4. **Move Programming Language**
```move
module aegis_pqc::quantum_crypto {
    /// Generate ML-KEM-512 keypair
    public fun mlkem512_keygen(): (vector<u8>, vector<u8>) {
        // Implementation would interface with Move's native functions
        let pk = vector::empty<u8>();
        let sk = vector::empty<u8>();
        (pk, sk)
    }
}
```

## 🔧 Algorithm Support

| Algorithm | Security Levels | Use Case | Blockchain Integration |
|-----------|----------------|----------|----------------------|
| **ML-KEM** | 512, 768, 1024 | Key Encapsulation | EVM precompiles, Substrate pallets |
| **ML-DSA** | 44, 65, 87 | Digital Signatures | Smart contract signing, transactions |
| **FN-DSA** | 512, 1024 | Digital Signatures | High-performance signing |
| **SLH-DSA** | 12 variants | Digital Signatures | Long-term security, stateless |

## 🏛️ Use Cases for Blockchain Projects

### **1. Quantum-Safe Smart Contracts**
```solidity
// Quantum-resistant DeFi protocol
contract QuantumSafeDEX {
    function quantumSecureSwap(address counterparty, uint256 amount) external {
        // Use PQC for key exchange
        bytes memory sharedSecret = establishQuantumChannel(counterparty);
        // Encrypt swap parameters and execute with quantum security
    }
}
```

### **2. Post-Quantum Blockchain Nodes**
```rust
// Substrate node with PQC consensus
impl ConsensusEngine for QuantumConsensus {
    fn validate_block(&self, block: &Block) -> bool {
        // Verify block signature with ML-DSA
        let is_valid = pqc.mldsa_verify("mldsa87", &validator_pk, &block_hash, &block_signature)?;
        is_valid
    }
}
```

### **3. PQC-Enabled Programming Languages**
```rust
// Core components for a PQC-enabled smart contract language
pub struct PqcEnabledLanguage {
    pqc_runtime: PqcInterface,
    gas_meter: GasMeter,
}

impl PqcEnabledLanguage {
    pub fn execute_pqc_operation(&mut self, op: PqcOperation) -> Result<Vec<u8>, String> {
        let gas_cost = self.calculate_gas_cost(&algorithm, operation_type);
        self.gas_meter.consume(gas_cost)?;

        match algorithm.as_str() {
            "mlkem512" => { /* keygen implementation */ }
            "mldsa44" => { /* signing implementation */ }
            _ => Err("Unsupported algorithm".to_string()),
        }
    }
}
```

## 📊 Performance & Gas Costs

| Operation | Algorithm | Gas Cost | Execution Time |
|-----------|-----------|----------|---------------|
| Key Generation | ML-KEM-512 | 50,000 | ~5ms |
| Signing | ML-DSA-44 | 30,000 | ~3ms |
| Verification | ML-DSA-44 | 20,000 | ~2ms |
| Encapsulation | ML-KEM-512 | 40,000 | ~4ms |

## 🧪 Testing & Validation

```bash
# Run comprehensive test suite
cd pqc/pqvm && cargo test

# Test EVM precompiles
cd evm/precompiles && cargo test

# Test Substrate pallet
cd substrate/pallet && cargo test
```

## 🚨 Security Considerations

1. **Quantum Threat Timeline**: Quantum computers capable of breaking classical cryptography expected by 2030-2035
2. **Hybrid Security**: Consider using both classical and PQC algorithms during transition
3. **Gas Optimization**: Monitor and optimize gas costs for your blockchain
4. **Audit Requirements**: All PQC implementations should undergo cryptographic review
