Suppose Alice has a public key with modulus 815153 and encryption exponent 91. Eve intercepts a ciphertext 766247from Bob that was encrypted using this key. She calculates 766247⋅941^91(mod815153)=143804 and asks Alice to decrypt this message as an authentication test. Alice responds with the decrypted message 167698 Find the plaintext without factoring Alice’s modulus.
In the Elgamal encryption scheme, Bob's public key is fixed, but Alice uses a fresh random i e {2,...,p – 2}, and hence a fresh random kg, whenever she wants to send Bob a message. What happens if Alice uses the same i for ecrypting multiple messages? Can Trudy recover any meaningful information from the ciphertexts?
Alice uses RSA to send a key to Bob for use in encryption of future messages. The key is the word "CINEMA" and the encoding from letters to numbers is done using the ASCII: A = 65... Z = 90, space = 99. The public parameters (n, e) = (9379, 11) are shared. Encrypt Alice's key word, using 2-letter blocks. Please show work.

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…
