Detailed explanation-1: -Confidentiality refers to encryption while integrity refers to digital signing. Confidentiality reduces the risk of someone understanding the message flowing across the Internet. With confidentiality specifications, the message is encrypted before it is sent and decrypted when it is received at the correct target.
Detailed explanation-2: -The main goal of encryption is to ensure data confidentiality, i.e., protecting data from being accessed by unauthorized parties. So, while encoding makes its conversion algorithms as public as possible, encryption should keep such algorithms private.
Detailed explanation-3: -There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.
Detailed explanation-4: -Public-key encryption thus provides for both confidentiality and authentication. The benefits of public-key encryption are clear. The sender and recipient no longer need to communicate previously, nor do they need to exchange private keys to send a communication that is signed and secure.
