Abstract
A method and apparatus for a satellite system. A satellite system is comprised of a communications system in a satellite and a number of computers associated with the satellite. The communications system is configured to receive first information and transmit second information from the satellite to a remote platform over a number of communications links. The number of computers is configured to identify a block of information for encryption from instructions in the first information. The number of computers is further configured to generate a key from a portion of the block of information based on the instructions. The number of computers is further configured to perform an exclusive OR operation on the block of information using the key to form a block of encrypted information. The number of computers is further configured to transmit the block of encrypted information.
