Answer / deepathi

Ciphering is the process of altering voice or data information with the intention of preventing its consumption or usage by unauthorized recipients. Ciphering involves the use of a data processing algorithm (formula program) that uses one or more secret keys that both the sender and receiver of the information use to encrypt and decrypt the information. Without the encryption algorithm and key(s), unauthorized listeners cannot decode the data or messages.
