Contextual Keying

Contextual keying is defined as the process of selecting an encoding key from context information that is either known or predictable about the target. A context-key is defined as the result of that process. The context information available about the exploit's target may contain any number of various types of information, dependent upon the attacker's proximity to the target, knowledge of the target's operation or internals, or knowledge of the target's environment.
