I'm not sure what asymmetric encryption has to do with this.
There are already protocols that are widely used in ham radio that support encryption. For example, DMR supports encryption (because DMR can also operate in commercial bands, under different laws), it's just not used for ham radio and I've never seen a ham turn it on. Wifi supports encryption, and ham radio operators using it in ham radio bands (with more power) actually turn encryption on but document the PSK publicly (in an attempt to keep the non hams out, but make the encryption more an encoding that anyone could decode).
In my experience, ham radio operators generally roughly follow the rules.
- n0ot 6y agoIs this explicitly allowed? I've always thought it would be cool if amateurs were allowed to encrypt their communications, so long as they provided the decryption keys regularly over the same channel. You could incorporate cryptographic signatures, diffie-helmann key exchanges, all kinds of fun stuff, and so long as you periodically transmit the decryption key, you're not hiding anything. I'm not sure what the legality of this is.
- throwaway3neu94 6y agoIt's thought to be legal but it is not explicitly allowed, and so it requires some legal interpretation and that is not court tested.
