Title

Confidentiality

Control

Confidentiality is the property whereby information is not disclosed to unauthorized parties. Secrecy is a term that is often used synonymously with confidentiality. Confidentiality using cryptography is achieved using encryption to render the information unintelligible except by authorized entities. The information may become intelligible again by using decryption. In order for encryption to provide confidentiality, the cryptographic algorithm and mode of operation must be designed and implemented so that an unauthorized party cannot determine the secret or private keys associated with the encryption or be able to derive the plaintext directly without using the correct keys.
