1. A method of communicating over a transmission medium using an iterated hash function, the method comprising the steps of:

  • determining that a first series of communications based on a first password has reached a predetermined minimum number of remaining hash function iterations;

    generating an initialization signal relating the first series of communications based on the first password to a second series of communications to be based on a second password, wherein the initialization signal is generated as a function of the results of applying a first number of hash function iterations to the first password and a second number of hash function iterations to the second password; and

    transmitting the initialization signal over the medium prior to commencing the second series of communications.
