Re: DSN authentication? (fwd)
by Lucky Green 17 Dec '03

Some of you may remember my post to the list a while back wondering which, if any, authentication is taking place on commands sent to space crafts such as the Mars Rover. Well, here is the official answer: "We use a private network and keep the protocol specs secret, therefore we don't have to worry about a thing". -- Lucky Green <mailto:shamrock@netcom.com> PGP encrypted mail preferred ---------- Forwarded message ---------- Date: Wed, 17 Dec 1997 12:14:35 -0800 (PST) From: Public Info <info(a)deepspace1.jpl.nasa.gov> To: Lucky Green <shamrock(a)netcom.com> Subject: Re: DSN authentication? Dear Mr. Green: I now have a response to your questions of authentication from one of our Deep Space Network Operations Managers, as follows: The commanding of any spacecraft is performed via a closed and secured network not accessed by the internet or the public. Direct connections provided by NASCOM connect the DSN sites to the project operations centers. There is no other branches nor interconnections available outside this circuit. Each project center determines the bit structure of each command sent, and not even the DSN sites that transmit the commands are aware of the format, protocols, etc. Command data is not stored at the sites to avoid sending commands inadvertently to the spacecraft. As a matter of fact, DSN policy is not to accept responsibility for manually sending commands even in case of a disaster. And, even within this closed circuit, command data is given the highest priority and treated as sensitive data and the command subsystems receiving and transmitting this data have been classified with the with the highest NASA security level. I hope this answers your question. Thank you for your interest.
