1. A method of processing a message using a cryptographic algorithm in a manner resistant to external detection of secret information, comprising the steps of:

  • receiving input data;

    generating a random value; and

    substantively altering the observable operation of said cryptographic algorithm while processing said input data, in accordance with said random value, frustrating the correlation of output power emissions with any meaningful internal processing.
