This is for Applied Cryptography... 4) Suppose we define a MAC RAW

4) Suppose we define a MAC RAW = (S,V) where S(km)-rawCBC(k,m). Explain a scenario that shows IRsw can be easily broken using a L-chosen msg attack (This attack scenario can proof that why the last encryption step must be included in ECBC-MAC).[1 point] 4) Suppose we define a MAC RAW = (S,V) where S(km)-rawCBC(k,m).
