Under Canadian laws, everything lies on the expectation of confidentiality. If you crypts the com line, you expect that no one will be able to listen (except the intended recipient). If someone break that expectation (unauthorized decryption), he break the law. If you speak out loud in a restaurant, you can't expect privacy... And if someone uses what you said in that restaurant, he didn't break the law.

The same apply to wireless (802.11 in our case), cellular, radio or satellite tv.

Why some of you are angry about security full disclosure? We have the right to know. Ok, script kiddies can use the information, but if I know how they proceed I will be able to stop them and/or detect them. When I detect misuse, I can report it. Sometime legal action can be taken against intruders. But... If I don't know how to stop and detect them, how I can report misuse and protect against? How IDS will work?

I don’t want to start a debate on full disclosure. Just let the information flow and chill.
