AES 128 in hardware under a buck

AES 128 in hardware under a buck

I'm currently working with low power radios in consumer electronics.  Zigbee/RF4C, Bluetooth low energy, etc.

The interesting thing is that there are chips which contain a processor, a 2.4GHz radio, and AES 128 in hardware.

For a few bucks or less.  Going into things like TV remote controls.  Great for protecting your keystrokes on a qwerty remote control when using TV like a computer. Makes you wonder about AES 128. ....

Also, adding a microphone (think Siri voice control) is becoming commonplace.  Which can be fun but the microphone is in a system which can be manipulated.  

As someone (DIRNSA ?) recently said, folks are bugging themselves.*

At least certain Sun workstations of old turned on an LED when the microphone was enabled. ....

It is now trivial to make a bursted, encrypted audio bug the size of the battery plus a little.
