# Quantum Side-Channel Leakage Verification

## Core Concepts

Q-LEAK provides a quantum algorithmic approach to verifying side-channel countermeasures. Traditional side-channel analysis requires extensive physical measurements; quantum methods can accelerate the verification process by leveraging quantum parallelism.

## Methodology

### Quantum Leakage Analysis

1. Model the cryptographic implementation as a quantum-accessible function
2. Use quantum amplitude estimation to estimate leakage metrics
3. Compare leakage against security thresholds

### Countermeasure Validation

1. Implement countermeasure (masking, shuffling, hiding)
2. Apply Q-LEAK to verify reduction in statistical distinguishability
3. Iterate until leakage is below acceptable threshold
