An information processor is installed onboard a seagoing vessel that has at least one onboard system, e.g., a weapon system, to carry out a mission that is defined by instructions originating at a remote location, e.g., mission data updates (MDU) data. The information processor is programmed to receive unencrypted data related to the mission. A secure communications terminal has a first hardwire connection to a public switched telephone network (PSTN) and a second hardwire connection to the information processor. The secure communications terminal receives encrypted data related to the mission over the first hardwire connection, converts the encrypted data to unencrypted data and supplies the unencrypted data over the second hardwire connection.
