If the keysize is "k", this attack uses only 2encryptions (and decryptions) (and "O"(2) memory in case a look-up table have been built for the set of forward computations) in contrast to the naive attack, which needs 2 encryptions but "O"(1) space.
If the keysize is "n", this attack uses only formula_4 encryptions (and formula_5 space) in contrast to the naive attack, which needs formula_1 encryptions (but only formula_7 space).
If the keysize is "n", this attack uses only formula_4 encryptions (and formula_5 space) in contrast to the naive attack, which needs formula_1 encryptions (but only formula_7 space).
