The European Space Agency (ESA) unveiled an experiment it hopes will overcome the problems that prevent encrypted communications between the Earth and orbiting spacecraft.
The Cryptographic ICE Cube, launched into orbit in April as part of the NG-11 mission, has been installed on the ISS' Columbus laboratory and is currently being controlled from the ground by researchers in the Netherlands.
ESA says the experiment has recently begun to return data that will be analyzed and shared with CERN. Full testing will begin later in August and is scheduled to run for at least a year.
The aim of the mission, says ESA software product assurance engineer Emmanuel Lesser, is to overcome the hurdles that solar radiation presents for encrypted communications. Specifically, the way encryption keys can be scrambled when radiation hits the memory chips doing the communicating while on orbital spacecraft.
"In orbit the problem has been that space radiation effects can compromise the key within computer memory causing ‘bit-flips’," he explained .
"This disrupts the communication, as the key on ground and the one in space no longer match. Up to now this had been a problem that requires dedicated, and expensive, rad-hardened devices to overcome."

There's a whole pile of WTFs around this which indicates it's more someone at the ESA playing than any real experiment. Firstly, if you're going to do something like this then you run a hardware and software combination that's likely to endure in that environment, e.g. a TMS570 + FreeRTOS, not a toy like the Pi with Linux that has enough trouble staying running on earth, let alone in space.
Secondly, to test this you don't need to put it into orbit, you just need a suitable source of radiation, e.g. a hospital Co60 source which is how we test our gear, where you can vary the parameters and see how different things work out. "Put it in orbit and see what happens" isn't an evaluation, it's more a "we can put stuff into orbit, what about this?".
