Struct CorrelationAttack 

pub struct CorrelationAttack {
    pub register_len: usize,
    pub init_state: Vec<bool>,
    pub agreement: f64,
    pub bias: f64,
    pub samples: usize,
}

The certified result of a correlation attack on one target LFSR: the recovered initial state and the statistical edge it carries. The init_state is a re-checkable witness — regenerate the LFSR from it and it reproduces the register the keystream leaks.

Fields

register_len: usize

The register length L (= taps.len()).

init_state: Vec<bool>

The recovered initial state — the L-bit LFSR seed that best correlates with the keystream.

agreement: f64

Pr[z = a] over the sample — the correlation p (or 1 − p if the leak is anti-correlated).

bias: f64

|agreement − ½| — the statistical edge; compare against spurious_bias_floor.

samples: usize

The number of keystream bits scored, n.

Trait Implementations

impl Clone for CorrelationAttack

fn clone(&self) -> CorrelationAttack

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CorrelationAttack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CorrelationAttack

fn eq(&self, other: &CorrelationAttack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
