In this video, I have explained asymmetric key cryptoghraphy (asymmetric cipher model in network security) concepts in network security and also explained elements (ingredients) of asymmetric key cryptography. How asymmetric key cryptography work?

Different keys are used for encryption and decryption, it is called asymmetric key cryptography. Public key used for encryption, private key used for decryption and vice versa. It is also known as public key cryptography.

Plaintext is the original message or data that is fed into the algorithm as input. Encryption algorithm performs various substitutions and transformations on the plaintext. Public & Private keys: This is a pair of keys that have been selected so that if one is used for encryption, the other is used for decryption. Ciphertext is the unreadable message produced as output. It depends on the plain text and secret key. Decryption algorithm takes the cipher text and the secret key and produces the original plain text.

Public key is distributed to all users and Private key is known to particular user only. There are two different Scenario of encryption model:
Public key used for encryption and private key used for decryption.
Private key used for encryption and public key used for decryption.
