Web13 de jul. de 2014 · To avoid nit-picking, let’s keep it simple and assume that an individual block cipher does not use an algorithm that loses some of the effective security a key provides. Also, let’s assume that no known attacks exist. Would it be more correct to claim that the effective security of that cipher is equal the key size, or is it half the key size?
