TranslationKey CJustificationThe conversion of a given plaintext into ciphertext form is called encryption. This form would be inunintelligible form till it is decrypted into plaintext form through decryption. Any message that isintelligible is considered to be in plaintext form.An encrypted form will not be intelligible without theuse of additional information. Hence, answer in Option C above is correct whereas the other answersare wrong.284.The mathematical function used for encryption & decryption is ______________.A. Binomial analysisB. Cryptographic AlgorithmC. Transcription AlgorithmD. Exponential functionKey BJustificationThe mathematical function used for encryption & decryption is called the cryptographic algorithm orCipher. Answer in Option B above is correct whereas the other answers are wrong. We have textbook solutions for you! The document you are viewing contains questions related to this textbook.

The receiver converts the ciphertext message back to its plaintext form. This part of the process is called decryption (sometimes decipherment ).
What system converts between plain text and ciphertext?In cryptography, algorithms transform plaintext into ciphertext, and ciphertext into plaintext. These respective processes are called encryption and decryption. The basis for using such a system is to ensure that the data can only be read by its intended recipient.
What is the process of converting from plaintext to ciphertext in the context of cryptography called?Encryption is the process of converting normal message (plaintext) into meaningless message (Ciphertext).
