**Chosen-plaintext attack**— A chosen plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker has the capability to choose arbitrary plaintexts to be encrypted and obtain the corresponding ciphertexts. The goal of the attack is to gain… …113

**Chaffing and winnowing**— is a cryptographic technique to achieve confidentiality without using encryption when sending data over an insecure channel. The name is derived from agriculture: after grain has been harvested and threshed, it remains mixed together with… …114

**Involution (mathematics)**— In mathematics, an involution, or an involutary function, is a function that is its own inverse, so that: f ( f ( x )) = x for all x in the domain of f . General propertiesAny involution is a bijection.The identity map is a trivial example of an… …115

**Mealy machine**— In the theory of computation, a Mealy machine is a finite state machine whose output values are determined both by its current state and the current inputs. The outputs change asynchronously with respect to the clock, meaning that the outputs… …116

**High-bandwidth Digital Content Protection**— (HDCP) is a form of digital copy protection developed by Intel Corporation to prevent copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High Definition Multimedia Interface (HDMI),… …117
