US Army Developing Encrypted Radar Waveform (thestack.com)

An anonymous reader writes: The U.S. army is working on an innovative technology for masking radar emissions in contested territory and environments with heavily congested radio bands. Effective radar system performance is critical in military operations, yet remains a challenge in locations under attack or in areas of high traffic density. Army researchers have now developed a noise-encrypted radar waveform called Advanced Pulse Compression Noise (APCN), which can be tuned in real-time to allow users to adjust radar performance depending on their surroundings. Research scientist, Mark Govoni explained: 'Having the ability to transmit a radar waveform that's continually changing, one that never repeats itself, and looks like noise, is extremely difficult to intercept....and remains anonymous to radar detectors.'

Here's an idea

Allow OTA updates only through a program (app) on a smartphone.

This achieves three important things;

1. The car has no remote communication capabilities (update via cable or at worst NFC that can be turned off in hardware!)

2. You can choose if you want to upgrade because you can choose to connect or not.

3. Be a much safer option for updates etc.

Let's not forget other motives manufacturers have...your data. Manufacturers can still get at their precious data for customers willing to share it.
