Bottom line the handset has to be able to decript it, so between the telco and the handset there is a common key at work.
Still if you don't trust your own goverment then why would they trust you.
Just wished some goverments were as open as they like us the public to be.
In the context of intercepting and storing your messages, trusting "your own government" means thousands of strangers, government employees and contractors alike, in this and future administrations, both now and as long as the data is stored (likely beyond your lifetime).
It means trusting that they won't leak that data intentionally, for political or personal gain, or by incompetence, under attack by hackers all over the world. (And let's face it, almost no one is competent when it comes to that level of attacks.)
If you send any information at all, business or personal, that you wouldn't want to be used against you, you can either trust all of these people, or you can use strong encryption and never worry about it again.
This! No communication is as secure as it could be if gives access to someone that is not an intended recipient.
It's not a matter of trust, it is a matter of design and common sense. I trust plenty of people, but I don't email them the passwords to all my accounts. Doing so would be an unnecessary risk with zero benefit even if they are 100% trustworthy (possible) and even if they are never compromised (extremely unlikely) because other people's systems are beyond my knowledge and my control. How can someone analyze risk under such circumstances?
* Do you think a secretive intelligence agency is going to announce that they were compromised?
* Even if they do, how much data are they going to provide on what exactly was stolen?
Of course it's hard to verify RIM's claims since the whole system is run by them.
But if they haven't put either of those in place already then it's too late. They'd be relying on customers updating the software themselves, which is unlikely - especially for many security conscious companies.
If you want security, do the encryption yourself.
RIM has been saying the same thing for years, that it "does not have the ability to provide its customers’ encryption keys"
