USSS Channel Bravo. Very old and very common.

They actually refer to it as BAKER. And I have heard it used for former POTUS protection after they leave office. It used to be used in Houston for the GHW Bush detail, but I haven't confirmed it lately...

DVP has gone the way of analog signals, DVP hasn't been heard on my Federal channels in many many years.

Actually, I don't know if DVP was ever used on federal channels. When digital encryption first started being used on federal radio systems, I always thought that they were using the federal DES encryption. Digital Voice Privacy, or DVP, was a less secure (shorter key) encryption solution that was sold to non-federal law enforcement by Motorola for a number of years. I think DVP was actually a Motorola trademarked product.

Now days, I think all federal radio encryption is at least AES, or something beyond that. But your point is made, Kenny...

I read somewhere that the PPD (presidential protection detail) now uses encryption called Keccak SHA-3 with a key length of 512 bits since April 2014. AES 256 is still approved for top secret information and is used in many federal agencies communications.
