All military and commercial avionics run over standard buses : MIL-STD-1553 and maybe also ARINC 429. US Military is very much into standards and believes in Kerckhoff's principle ( http://en.wikipedia.org/wiki/Kerckhoffs%27s_principle ), ie. no security by obscurity. They protect information by standard, well vetted crypto protocols and young men with large guns. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
