Detailed Description

Masked implementation of the TinyJAMBU permutation.

Macro Definition Documentation

#define TINYJAMBU_MASKED_ROUNDS

(

steps

)

((steps) / 128)

Converts a number of steps into a number of rounds, where each round consists of 128 steps.

Parameters

steps

The number of steps to perform; 384, 1024, 1152, or 1280.

Returns

The number of rounds corresponding to steps.

Function Documentation

void tiny_jambu_permutation_masked	(	mask_uint32_t	state[TINY_JAMBU_MASKED_STATE_SIZE],
		const mask_uint32_t *	key,
		unsigned	key_words,
		unsigned	rounds
	)

Perform the TinyJAMBU permutation in masked form.

Parameters

state	TinyJAMBU state to be permuted in masked form.
key	Points to the masked key words.
key_words	The number of words in the masked key.
rounds	The number of rounds to perform.

The number of key words should be 4 for TinyJAMBU-128, 12 for TinyJAMBU-192, and 8 for TinuJAMBU-256. The TinyJAMBU-192 key is duplicated so that the key_words parameter is a multiple of 4.
