Question 4 The question is about public key cryptosystem. (a) Explain the RSA algorithm for encryption and decryption functions of the public key Cryptosystem. (8 marks) Assume that Alice has public and private RSA keys n = 85, e = 7 and d =55 while Bob has public and private RSA keys n=77, e = 17 and d = 53. (b) (c) Assuming the role of Bob, implement suitable algorithms to encrypt and sign the message m = 19 to send to Alice. (6 marks) Demonstrate the steps that Alice takes to recover the original message. (6 marks) Question 4 The question is about public key cryptosystem.
