Reference no: EM13328977

Using the English alphabet (i.e., mod 26 arithmetic) let plaintext = {p1, p2,... , pn} and corresponding ciphertext = {c1, c2,... , cn}. Suppose the encryption function is ci = pi + 6 (mod 26). If you receive the ciphertext message ASAIMXGJAGZKYINUUR and are asked to recover the plaintext. answer the following questions: a). What is the decryption function, b). What is the decrypted plaintext? c). What are some weaknesses of this cipher?
