Anyone knows what kind of encryption they use on top of this?
- technimad 6y agoProbably none. Why should telemetry data sent from Mars be encrypted? Encryption makes the system more complex and requires more computations and power on Mars.
- gapipro 6y agoOk for telemetry data I agree, but what about remote control and other communication channels with rover?
- yellowapple 6y agoI would expect cryptographic signing to be more relevant for remote control than trying to obfuscate the remote control data entirely.
- augusto-moura 6y agoI'm pretty sure telemetry is encrypted. Telemetry is not only position or velocity, there's a bunch of other information from sensors that should be handled with secrecy. Also gives more flexibility with announcements, given that the mission can fail anytime it's bad if some random person leaks that the rover stopped working suddenly or had a RAD
- augusto-moura 6y agoWell, I don't think there's a confirmed source, because of obvious reasons. Probably the same used on earth by us common folk. Maybe AES because of the deep government roots
