Side-channel security

Side-Channel Attack Playground

Compare safe local simulations of timing, cache, and power-style leakage. See how secret-dependent behavior can reveal hints even when the cryptographic output itself is not directly exposed.

Safe simulation only

This module uses deterministic educational signals. It does not probe external systems, measure real hardware, or attack real services.

Leakage summary

The signal is a safe deterministic teaching value, not a real clock, cache probe, or hardware measurement.

Timing leakage

Timing side channels infer information when secret-dependent work takes measurably different time.

Signal samples

Higher bars indicate stronger observable side-channel signal in this educational scenario.

Mitigation guidance

Use constant-time comparison for tokens, MACs, and signatures.

Keep execution work independent of matching prefix length.

Avoid secret-dependent branches and early returns.

Use audited cryptographic libraries for sensitive operations.

Rate-limit and monitor authentication or oracle-like endpoints.
