Module side_channel 

Side-channel timing test framework.

Provides utilities for measuring operation durations and detecting timing-based information leakage. Used to verify constant-time guarantees of cryptographic operations.

Structs

TimingSample

A single timing measurement.

TimingStats

Statistics over a set of timing samples.

Functions

is_constant_time

Check if two groups have consistent timing (ratio < threshold).

measure

Collect timing samples for an operation.

measure_n

Collect N timing samples for an operation.

stats

Compute statistics over timing samples.

timing_ratio

Compare timing distributions between two groups. Returns the ratio of max/min mean. A ratio near 1.0 suggests constant-time; a large ratio suggests timing leakage.
