Detailed Description

As a utility class for KeccakFDCLC, this class lists the output row patterns (differences or linear masks) compatible with a given row input pattern through either χ or χ^-1. The main attribute is values, which lists all the corresponding output row patterns. Associated with each output value (same index in the vector), its propagation weight is in the vector weights. Note that the values are sorted in increasing weight order, so one can start looking for the outputs with lowest weight first. The maxWeight and minWeight attributes indicate the maximum and minimum propagation weights present, respectively.

Constructor & Destructor Documentation

ListOfRowPatterns::ListOfRowPatterns

(

)

[inline]

This constructor initializes the output patterns to the empty set.

Member Function Documentation

void ListOfRowPatterns::add	(	RowValue	aValue,
		int	aWeight
	)

This function adds a possible output pattern, along with an associated propagation weight, while inserting it at the right place to ensure that they are listed with increasing propagation weights.

Parameters:

	aValue	An output pattern.
	aWeight	Its associated propagation weight.

void ListOfRowPatterns::display

(

ostream &

fout

)

const

This function displays the possible patterns and their weights.

Parameters:

fout

The stream to display to.

Member Data Documentation

vector<RowValue> ListOfRowPatterns::values

The list of output row patterns (differences or selection vectors) compatible with a given row input pattern.

vector<int> ListOfRowPatterns::weights

The list of propagation weights, for each row pattern, i.e., weights[i] is the weight of values[i].

bool ListOfRowPatterns::minMaxInitialized

True iff maxWeight and minWeight are meaningful.

int ListOfRowPatterns::maxWeight

The maximum propagation weight in weights.

int ListOfRowPatterns::minWeight

The minimum propagation weight in weights.
