Detailed explanation-1: -Question 22 1 pts Suppose (n, d) = (55, 3) is the private key of an RSA cryptosystem: If the received ciphertext is C = 49 what is the corresponding plaintext? 3 4 10 14. So, the public key is $(n, e) = (55, 27)$.
Detailed explanation-2: -At the center of the RSA cryptosystem is the RSA modulus N. It is a positive integer which equals the product of two distinct prime numbers p and q: RSA modulus: N = pq.
Detailed explanation-3: -The public key is used to encrypt the message while the private key is used to decrypt the message.
Detailed explanation-4: -Answer => The requirement is to encrypt the message m=88 using RSA we are provided with p = 17, q =11 and e =7 Method: N = p x q N = 17 x 11 N = 187 (n) = (p-1) x (q-1) =>(17-1) x (11-1) =>16x10 (n) = 160 The message is given a…
