And for DMR, it's interesting. So DMR uses link layer privacy, and that basically secures a transmission by an exo-ring or a key stream onto a coded and be voice frame. And the way it works is the DMR association, so they're the ones that are in charge of the standard. They allow for cypher cores and different manufacturers to implement them differently. So for example, Motorola, they have basic privacy, which is basically a short key scrambler, and they also have something called enhanced privacy, which utilizes the RC4 stream cypher. So that's a 40-bit cypher. And DMR can also support the AES256 block cyphers, similar to what P25 would use. But again, the implementation is up to the specific vendor. And typically the way the keys are managed is you have an
