Module sidechannel 

Side-Channel Resistance Verification

This module provides tools for verifying that cryptographic implementations are resistant to various side-channel attacks including timing attacks, power analysis, and cache-timing attacks.

Features

• Timing attack detection: Statistical analysis of execution times
• Constant-time verification: Verify operations take constant time
• Data-dependent timing detection: Identify timing variations based on input
• Cache-timing analysis: Detect cache-based side channels
• Power analysis simulation: Basic power consumption pattern analysis
• Leakage quantification: Measure information leakage through side channels

Example

use chie_crypto::sidechannel::{SideChannelAnalyzer, TimingTest};

// Create analyzer
let analyzer = SideChannelAnalyzer::new();

// Test an operation
let test = TimingTest::new("test_operation", 100);
let results = analyzer.analyze_timing(test, |data| {
    // Your cryptographic operation here
    let _ = chie_crypto::constant_time_eq(&data[..16], &data[16..32]);
});

// Check timing statistics
assert_eq!(results.test_name, "test_operation");
assert_eq!(results.num_samples, 100);
println!("Leakage score: {}", results.leakage_score);
