KDD - (Knowledge Discovery in Databases) - A mathematical, statistical, and visualization method of identifying valid and useful patterns in data.
kernel - The core of an operating system, a kernel manages the machine\'s hardware resources (including the processor and the memory) and provides and controls the way any other software component accesses these resources.
key - The input that controls the operation of the cryptographic algorithm. It determines the behavior of the algorithm and permits the reliable encryption and decryption of the message.
key - A discrete data set that controls the operation of a cryptography algorithm. In encryption, a key specifies the particular transformation of plaintext into ciphertext, or vice versa, during decryption. Keys are also used in other cryptographic algorithms, such as digital signature schemes and keyed-hash functions (also known as HMACs), which are often used for authentication and integrity.
key clustering - When different encryption keys generate the same ciphertext from the same plaintext message.
key length - The size of a key, usually measured in bits, that a cryptographic algorithm uses in ciphering or deciphering protected information.
keystroke monitoring - A type of auditing that can review or record keystrokes entered by a user during an active session.
