I can't post in the tavern due to the mods otherwise I would have posted this in the Off topic Wireless sub forum. I have a question about KVLs (Key variable Loaders) and just want the low down on why you need to use a separate piece of equipment to upload an encryption key to a radio? Why can't you just use the CPS (software that programs the radio) to add an encryption key? I guess it might have something to do with FIPS, but without going through technical jargon and such I just want a simple answer. I have looked though Google and have read patents and other sites and couldn't find my answer. However, I did find a really nice PDF on encryption that was created by a user over at batlabs back in 2006. I can't find the original link, but I uploaded the PDF to my Dropbox. https://www.dropbox.com/s/yihtzvk371j75uv/encryption.pdf?dl=0
TIA for answers on KVLs.
