Answer 2

If the sender encrypts the message with her private key, it achieves the purpose of confidentiality and authentication. (Option b)

• The process of encryption allows the user to protect the data from getting accessed by third parties.
• It serves as a confidentiality provision and also takes into account the authentication factor.
• All important information can be shared while protecting it from being stolen or misused.
• Only the originator and the chosen receiver can access the data using a public and a personal key.
