Abstract
Layered semantic security provides a high degree of security for a mobile device based upon contextual awareness that dynamically changes based upon interaction between a user and a near communication device, which in turn interacts with a network, which ultimately interacts to a far communication device. Generating a shared secret key with a master secret and changing contextual information based on context awareness provides immunity to chosen plain text attacks by providing semantic security at each layer. Thereby, relying upon the overall robustness of the layering of semantic security, processing and power resources consumed can be advantageously adjusted dynamically to enhance concurrent use and service life of a mobile communication device.
