subject- cryptography/security engineering

Alice and Bob have securely established two symmetric keys K1 and K2. They have also agreed on the choice of ciphers. Suppose Alice wants to send the message m to Bob while ensuring both confidentiality and data origin authentication (so, achieve authenticated encryption). Which one of the following should she send to achieve that?

Select one:

MACK2(m||EncK1(m))

None of the these.

The result of encryption of m using AES in Counter Mode.

EncK1(MACK2(m))

The result of encryption of m using AES in CBC Mode.
