1. A remote digital firing system for firing of a remote mission payload, comprising:a firing circuit communicatively coupled to and operative to fire the remote mission payload; a firing control panel communicatively linked to said firing circuit; and a digital code plug configured to be integrated in communicative combination with said firing circuit and said firing control panel; wherein said firing circuit is operative, with said digital code plug integrated in communicative combination therewith, to generate and write one-time random session variables to said digital code plug and to simultaneously store said one-time random session variables internally in said firing circuit; wherein said firing control panel is operative, with said digital code plug integrated in communicative combination therewith, to generate and transmit messages having said one-time random session variables embodied therein to said firing circuit; and wherein said firing circuit validates said messages by comparing said one-time random session variables embodied in said messages with said internally stored one-time random session variables prior to firing the remote mission payload. 2. The remote digital firing system of claim 1 wherein said firing circuit includes a hardware random noise generator that is operative to generate said one-time random session variables.3. The remote digital firing system of claim 1 wherein said one-time random session variables include an ARM code for arming said firing circuit and a FIRE code for firing said armed firing circuit.4. The remote digital firing system of claim 1 further comprising:a predefined communication protocol that defines types, formats, contents, cryptographic requirements, and sequencing of said messages transmitted by said firing control panel to said firing circuit and types, formats, contents, cryptographic requirements, and sequencing of messages transmitted by said firing circuit to said firing control panel. 5. The remote digital firing system of claim 4 wherein said types of said messages transmitted between said firing control panel and said firing circuit include status messages, request-challenge messages, command messages, and verification messages.6. The remote digital firing system of claim 5 wherein the format of said request-challenge messages, said command messages, and said verification messages includes a message-originator identification character, one or more characters for specifically identifying each of said request-challenge messages, said command messages, and said verification messages, and a data block.7. The remote digital firing system of claim 6 wherein said request-challenge messages are transmitted between said firing control panel and said firing circuit prior to transmitting said command messages between said firing control panel and said firing circuit.8. The remote digital firing system of claim 7 wherein said firing control panel is operative to transmit said command messages to said firing circuit and said firing circuit is operative to transmit said verification messages in response thereto.
