Two companies would like to communicate confidentially online. They also seek integrity and authenticity of the communication between each other. They require secret-key cryptography to achieve these goals. It is important for the companies that the ciphertexts exchanged are authentic and have not been altered in transit. Note that the communication between the companies comes in the form of short messages which would fit into one plaintext block of AES-128. Which of the following solutions is ideal for this scenario, where the companies share 2 secret keys, k1 which they can use for encryption and k2 which they can use for issuing and verifying MACs? Choose only 1 answer. O 1. T=HMACK2 (M) 2. C= AES-128-ENCk1(T) 3. Send C and T to the other company O 1.C-AES-128-ENCk1(M) 2. T-HMACK2(M) 3.

Alice and Bod have decided to use a symmetric encryption algorithm. They have some assumptions about their messages:- Messages only contain capital letters (i.e. A to Z)- The length of their shared key must be greater than or equal to the length of the plaintext- They assign each letter a number as follows: (A,0), (B,1), (C,2), (D,3),…, (Z,25)Their algorithm combines the key and the message using modular addition. The numerical values of corresponding message and key letters are added together, modulo 26. For example, if the plain text is “HELLO” and the key is “SECRET” then the encrypted message is calculated as following:Since the length of the plaintext is 5, we just need the first 5 letters of the key (i.e. “SECRE”), then for each letter, we should add corresponding letters in both the plaintext and the key modulo 26.Plaintext: H (7) E (4) L (11) L (11) O (14)Key: S (18) E (4) C (2) R (17) E(4)Cipher: Z (25) I (8) N(13) C(2) S (18) Write a program in Python, C/C++ or JavaScript to…
