Simplified Model of Symmetric Encryption This model explains the process of encryption and decryption. Basically it simplifies how plaintext can be converted to ciphertext, send over the network and revert back to plaintext, with the help of a key. This model mainly consists of 5 ingredients, which are briefly explained below. Plaintext: Plaintext is nothing but original message need to pass. Secret Key: Secret key is input to encryption algorithm which depends on secret key, encryption algorithm will produce the different output for plaintext. Note: The receiver must have the secret key to successfully decrypt the message. Encryption Algorithm: This encrypts the plaintext based on various calculation written in algorithm and secret key. Cipher Text: Ciphertext is encrypted format of plaintext.

Note: Ciphertext is a changed format of a plaintext after encrypting it, it can be either in numerical form or in scrambled alphabetic order.
