Explain the process for transmitting the secure data using cryptography.

Cryptography is known for “secret writing“. The original message before being transformed is called plain text after the message is transformed, it is called cipher text. An encryption algorithm transforms the plain text to cipher text and a decryption algorithm
transforms the cipher text back to its original form. The sender uses an encryption algorithm and the receiver uses a decryption algorithm. It will often be useful to have a notation for relating plain text, cipher text and keys. We will use C=EK (p) to mean the encryption of the plaintext p using key K gives the cipher ___ ________ __________ ___ ________ _____ _______ _______ ______ ____ ________.
