____ are usually used in conjunction with nonsecret parameters to derive one or more keys from a common secret value.
A) TLS
B) EVPs
C) KDFs
D) MACs

Question

Quizplus · Accepted Answer

KDFs (Key Derivation Functions) are specifically designed for deriving one or more cryptographic keys from a common shared secret value. They are commonly used in conjunction with non-secret parameters like salt or context information to produce strong and unique keys for various cryptographic operations. TLS (Transport Layer Security) is a security protocol that provides encryption, authentication, and integrity of data, but it uses a combination of symmetric and asymmetric encryption keys, not just key derivation. EVPs (Enveloped Public Keys) are a type of public key cryptography used for secure transmission of data, not key derivation. MACs (Message Authentication Codes) are used for verifying the authenticity and integrity of messages, and not for deriving keys.
