Question 1 (5 marks) The major goal of cryptography is to prevent date from being read by any third party. Most transmission systems use a private-key cryptosystem. This system uses a secret key to encrypt and decrypt data which is shared between the sender and receiver. Required: Explain the details of the encryption and decryption process algorithms in a symmetric key cryptography system. Public-key cryptography, or asymmetric cryptography, is another encryption scheme. Discuss in detail public key cryptography and why is it important
