Radio has a lot more to it than just keys. For example, frequency hopping is a big thing, and which frequencies it jumps between, when, and why (i.e. as some sort of anti jamming strategy) are all important details which could be established by inspecting the equipment.
That said, the mention of the Motorola programming software does make this sound more like a base security/policing problem than actual operational infrastructure.
- Dah00n 3y agoSurely frequency hopping patterns is tied to the key and not hard coded? That would be pretty stupid.. but what do I know.
- DropInIn 3y agoWouldnt you just have another key as a seed for the hopping?
- sockaddr 3y agoI don’t understand how this is security. Wouldn’t an adversary just listen on all channels and pick up the rest of the communication on the newly detected frequency?
- aethros 3y agoFrequency hopping is actually not considered a secure communication method in military circles, nor is it designed to be. Frequency hopping is designed to provide robust communication during electronic warfare scenarios (jamming).
