Okay, and I'm almost done. So P25 Tetra DMR, let's talk about their encryption and the cryptographic protection of supply. So P25, it has end to end encryption, E2EE, and that's within the subscriber unit, right? So the radio itself. It uses an AES-256 bit encryption, and it's actually the lowest standard that's required for security. It requires a secure interoperability typically. There are some older legacy units that I was mentioning, and they use a 56-bit DES, that encryption standard algorithm. And as far as key management goes, they have a TIA-102 standard, and that basically defines the over-the-air re-keying that they can do from key management facilities. And that's basically all the other risks to that. So the other thing to note is that Motorola can see with the C-Sharing.
