(I) Like DES, AES also uses Feistel Structure. One or more of the following security violations can take place. Digital signature scheme changes the role of the private and public keys, Private and public keys of only the sender are used not the receiver. Due to the fact that sub-processes in each round are carried out in reverse order, as opposed to a Feistel Cipher, the encryption and decryption algorithms must be developed separately, despite the fact that they are extremely closely connected. 101.
