1. A method for performing layered semantic security between a near communication device and a far communication device, comprising:

  • collecting first changing contextual information regarding the near communication device;

    characterizing a first security vulnerability based upon the first changing contextual information;

    collecting second changing contextual information for a plurality of communication links between the near communication device and the far communication device, wherein the plurality of communication links include a near communication link between the near communication device and a near network interface;

    characterizing a second security vulnerability based on the second changing contextual information;

    selecting a cryptographic protocol based upon the first and second security vulnerability characterizations; and

    the near communication device establishing a secure communication with the far communication device by employing the selected cryptographic protocol in at least one communication link of the plurality of communication links.
