Today’s RF satellite communication technology uses millimeter-wave phased-array systems, and the basic problem statements haven’t changed. Network and satellite security risksRobust security measures for lunar and satellite networks are necessary to prevent sensitive information from being obtained by nation states or hackers. “The satellite security challenge is one of high interest and importance to the U.S. government,” said Scott Best, senior technical director of silicon IP at Rambus. ConclusionBoth government and private companies are taking steps to ensure data security as networks in space grow more complex with more use cases. Whether in space or on Earth, companies have to prove the same kind of capabilities, reliability, and security mechanisms.
