What (who) is covert channel leakage - definition
TYPE OF COMPUTER SECURITY ATTACK THAT CREATES A CAPABILITY TO TRANSFER INFORMATION OBJECTS BETWEEN PROCESSES THAT ARE NOT SUPPOSED TO BE ALLOWED TO COMMUNICATE
Covert channels; Timing channel; Timing channels
Covert channel
In computer security, a covert channel is a type of attack that creates a capability to transfer information objects between processes that are not supposed to be allowed to communicate by the computer security policy. The term, originated in 1973 by Butler Lampson, is defined as channels "not intended for information transfer at all, such as the service program's effect on system load," to distinguish it from legitimate channels that are subjected to access controls by COMPUSEC.
Leakage (electronics)
GRADUAL TRANSFER OF ELECTRICAL ENERGY ACROSS A BOUNDARY NORMALLY VIEWED AS INSULATING
Leakage current; Leakage (semiconductors); Transistor leakage current; Dielectric leakage; Leakage power; Leaking electricity; Leak resistance; Leakage resistance; Leak current
In electronics, leakage is the gradual transfer of electrical energy across a boundary normally viewed as insulating, such as the spontaneous discharge of a charged capacitor, magnetic coupling of a transformer with other components, or flow of current across a transistor in the "off" state or a reverse-polarized diode.
Leakage inductance
LEAKAGE INDUCTANCE DERIVES FROM THE ELECTRICAL PROPERTY OF AN IMPERFECTLY-COUPLED TRANSFORMER
Leakage flux; Leak inductance; Leakage reactance; Inductive circuit model of transformer
Leakage inductance derives from the electrical property of an imperfectly-coupled transformer whereby each winding behaves as a self-inductance in series with the winding's respective ohmic resistance constant. These four winding constants also interact with the transformer's mutual inductance.
