AES Encrypted Traffic Through Hytera HR1062

[robertsdoug]

I noticed that Hytera sells a AES encryption license for the repeater. However, if the Radio is already support encryption, and they already have a license, will the repeater pass the encrypted traffic, or does it also need to have the license? I wasn’t sure if the license is necessary for the repeater to, simply pass the encrypted traffic, or if that license is only required for the microphone attached to the repeater to be able to speak encrypted.

The DMR repeater isn't smart enough to know whether you're talking English, Chinese, AES encrypted or not, it's all one's and zero's. A repeater AES license is typically so you can listen/talk on an encrypted channel at the repeater itself. This is of marginal use unless you intend to participate in encrypted traffic from the hot and noisy repeater room. It could also be seen as a security flaw as anyone with a key to the repeaters location can now just waltz in and turn up the volume knob.

Thanks. After I posted this, I was able to get an AES licensed Radio and test this out and indeed, the simply passes through the traffic. It’s confusing when the repeater manufacturers have all of these licenses for both the subscriber units as well as the repeater units.

It was fun times when the Motorola XPR series was backdoored by some clever Germans who shared the goodness and so people were taking XPR's and adding expensive EID's left right and center.
