1. A remote digital firing system for firing a remote mission payload, the remote digital firing system comprising:

  • a firing circuit communicatively coupled to and operative to fire the remote mission payload;

    a firing control panel communicatively linked to the firing circuit; and

    a digital code plug configured to be integrated in communicative combination with the firing circuit and the firing control panel;

    wherein the firing circuit is operative, with the digital code plug integrated in communicative combination therewith, to generate and write one-time random session variables to the digital code plug and to simultaneously store the one-time random session variables internally in the firing circuit;

    wherein the firing control panel is operative, with the digital code plug integrated in communicative combination therewith, to generate and transmit messages having the one-time random session variables embodied therein to the firing circuit;

    wherein the firing circuit validates the messages by comparing the one-time random session variables embodied in the messages with the internally stored one-time random session variables prior to firing the remote mission payload; and

    wherein the one-time random session variables includes a SAFE/DISARM code for disarming the firing circuit.
