Member Function Documentation

virtual findKey_LengthBasedResult LengthAttackBase::findKey_LengthBased	(	int	N,
		const vector< Word > &	A1,
		const vector< Word > &	A2,
		const vector< Word > &	B,
		int	sec = 9999999,
		ostream &	out = cout
	)			[pure virtual]

Attack on an instances of the AAG protocol.

Executes a length-based attack on an instance of the AAG protocol

Parameters:

	N	- rank of the braid group (number of strands)
	A1	- Alices subgroup generators
	A2	- Alices subgroup generators conjugated by Bob's private key
	B	- Bob's subgroup (Bob's private key belongs to it)
	sec	- amount of time (in seconds) given to procedure to finish

Returns:

- Returns findKey_LengthBasedResult::SUCCESSFULL if the attack succeeds, findKey_LengthBasedResult::FAILED if the attack fails and findKey_LengthBasedResult::TIME_EXPIRED if the time limit is exceeded

Implemented in LengthAttack_A1, LengthAttack_A2, and LengthAttack_A3.
