Can we use EED with 2 keys (K1 K1 K3) rather than EDE (k1,k2,k1)? We measure the strength of DES by the effort (in terms of the number of tries) in finding some K1 & K2 to match a known plaintext and ciphertext pair. Will EED have the same strength as EDE? Which one is stronger?

Can anyone please help me with this?
