1. A method for applying adaptive security to a data stream, comprising the steps of:

  • identifying a desired security level range and a desired actual security level which falls within the desired security level range for communicating a data stream from a send host to a receive host;

    determining an actual security level in the receive host based upon the availability of a number of security processor operations;

    communicating the actual security level from the receive host to the send host;

    generating a plurality of data packets associated with the data stream in the send host, the data packets having an authentication header including the desired security level range and the actual security level;

    reallocating computing resources at the receive host if data packets cannot be verified at the desired actual security level with a current allocation of resources; and

    verifying the data packets at the actual security level, the actual security level being within the desired security level range.
