What Is Data Encryption

Encryption is the act of converting a message into a coded format that is unintelligible to users. When an encrypted message arrives at its destination, it is decrypted, that is, converted back to its original format.

Data Encryption

Encryption does not increase the number of bits in the data, but it adds processing time to the task of sending a message. Because data is compressed during encryption, however, lost processing time may be bought back, since less data is being sent across the network. When data is compressed, there is also a moderate boost to security, because the data is somewhat scrambled during compression.
