A straightforward implementation of 3DES would be in practice C = E k1 (D k2 (E k1 (m))). What if k1 = k2? Select one: O a. Will be the same as 2DES O b. None of the choices O C. More complex implementation of DES O d. Cannot set k1 to be equal to k2 e. Will be the same as 1DES O f. We cannot implement 3DES in practice
