What are two differences between ECC and RSA? (Choose two.)

A: Key generation in ECC is slower and more CPU intensive than RSA. B: ECC can have the same security as RSA but with a shorter key size. C: ECC cannot have the same security as RSA, even with an increased key size. D: Key generation in ECC is faster and less CPU intensive than RSA. E: ECC lags in performance when compared with RSA.
