how do you do 1-3

1. [1 pt] For the given plaintext, what would be the state (intermediate cipher) after the first round of DES? A plaintext block right after the initial permutation (01010000010011000100000101001001010011100101010001000101 01011000) 48 bit sub-key for the first round (1101011100001010010111010010001010000011 11010101) 2. [1 pt] Describe the differences between DES and AES. What are the reasons that AES is stronger than DES in terms of security? 3. [1 pt] Suppose you, as an attacker, observe the following 32-byte ciphertext Cl (in hex) 4D 11302813 C6 8C EB 312120 B0 70 B4 C3 B4 FA 3A 20120213 1C FD C5 440725 D3 96 IF 74 3.
