Detailed Description

Permutations that are used by the KNOT AEAD and hash algorithms.

Typedef Documentation

typedef void(* knot_permute_t)(void *state, uint8_t rounds)

Generic pointer to a function that performs a KNOT permutation.

Parameters

state	Points to the permutation state.
round	Number of rounds to perform.

Function Documentation

void knot256_permute_6	(	knot256_state_t *	state,
		uint8_t	rounds
	)

Permutes the KNOT-256 state, using 6-bit round constants.

Parameters

state	The KNOT-256 state to be permuted.
rounds	The number of rounds to be performed, 1 to 52.

The input and output state will be in little-endian byte order.

void knot256_permute_7	(	knot256_state_t *	state,
		uint8_t	rounds
	)

Permutes the KNOT-256 state, using 7-bit round constants.

Parameters

state	The KNOT-256 state to be permuted.
rounds	The number of rounds to be performed, 1 to 104.

The input and output state will be in little-endian byte order.

void knot384_permute_7	(	knot384_state_t *	state,
		uint8_t	rounds
	)

Permutes the KNOT-384 state, using 7-bit round constants.

Parameters

state	The KNOT-384 state to be permuted.
rounds	The number of rounds to be performed, 1 to 104.

The input and output state will be in little-endian byte order.

void knot512_permute_7	(	knot512_state_t *	state,
		uint8_t	rounds
	)

Permutes the KNOT-512 state, using 7-bit round constants.

Parameters

state	The KNOT-512 state to be permuted.
rounds	The number of rounds to be performed, 1 to 104.

The input and output state will be in little-endian byte order.

void knot512_permute_8	(	knot512_state_t *	state,
		uint8_t	rounds
	)

Permutes the KNOT-512 state, using 8-bit round constants.

Parameters

state	The KNOT-512 state to be permuted.
rounds	The number of rounds to be performed, 1 to 140.

The input and output state will be in little-endian byte order.
