Explanation
The following are the goals of cryptography: 1.Confidentiality: It makes sure that the message remains private and cannot be accessed by any unauthorized user when transmitted between two or more parties. There are two types of cryptosystems that ensure message confidentiality. They are as follows: Symmetric key cryptosystem: It uses the shared key that is available to all the users of the Public key cryptosystem: It makes use of a combination of public and private keys for each user of the cryptosystem. 2.Integrity: It makes sure that the message remains unaltered when transmitted between two or more parties. If the goal of integrity is attained, the recipient is ensured that the received message is identical to the message that was sent. 3.Authentication: It verifies the user's identity. 4.Nonrepudiation: It assures the recipient that the message was really sent by the sender and someone is not masquerading as the sender.
