ABSTRACT:
The present invention is directed to a remote digital firing system for firing of a remote mission payload that includes 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 variable 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.
