Amateur Radio and Encryption Canada

 Why would anyone want to use encryption on ham radio? comment below.

That said, there has never been any expectation of privacy for communications under amateur license.

In Canada, from what Industry Canada has said, it is legal to use encryption on the amateur frequencies as long as you use a key that is published. If you don't make the key available to everyone, you can't encrypt.

Interesting how Canada and the US are different on encryption in the ham bands. What's ironic, is that if the encryption key is publicly available to anyone/everyone, doesn't that negate the purpose of encryption? That's like putting a sign on your front door that says "Door is locked so that no one may enter. There is a spare key under the door mat. Come on in."

Since Amateur Radio is not designed to be a private means of communication, why would anyone need/want to use encryption in the ham bands, except for experimentation? No answer needed, that was a rhetorical question, and one that has been beaten to death.

Conclusion:

Encryption on amateur radio is prohibited in most countries. There are some exceptions, in some countries, and for some specific use cases. You'll need to consult your local rules.

Some countries (Australia being an example) allow encryption in emergency communicationsand relevant training activities.

Some countries (US, for example) allow encryption for transmitting control commands to satellites, so that unauthorized stations can be prevented from causing harm to the satellite.

Some protocols used in digital networking (IPSEC, SSL/TLS) allow you to disable traffic encryption (using a "none" cipher), but still use cryptographic algorithms such as HMAC to do strong authentication and tampering prevention. Doing that does not conceal the contents of the traffic, so it's allowed, and sufficient for many use cases such as remote commands to satellites, or other restricted-access services.
