In the context of HAM radio transmissions, encryption includes voice scrambling methods that we wouldn't nowadays consider secure encryption. There used to be a lot of analogue voice scramblers and voice inversion tools. I think you can still buy them. Generally, there is a prohibition against obscuring transmissions on HAM radio. (Or at least I think so, I'm not a HAM operator myself.)
- giantg2 6y agoYep. There are some manufacturers that offer AES 256 encryption capable encryption too. I think that's still generally secure.
- giantg2 6y agoWhy is this downvoted? Kenwood is one of the manufactures that has AES 256 radios capable of transmitting in the ham bands. NIST still considers AES 256 secure.
- JshWright 6y agoNot sure why it was being downvoted, but saying "AES 256" is secure is both true and meaningless. It's a low level building block of cryptosystems, and there are countless examples of AES based systems being compromised because the system built around it had flaws.
- giantg2 6y agoYeah, I guess the algorithm is secure but how it's implemented may not be. I think the NSA was involved with at least some radio manufacturers implementation, so there could be a backdoor.
