bluetooth is a disaster, and it's paying my (figurative) bills right now. i love it!
one day, people will learn to secure all wireless connections before even putting them on the market. one day.
The assumption that they
can be secured is an iffy one, IMHO. I'd make the argument that any time you're deliberately broadcasting your data, they're insecure. Period. No matter what fancy new encryption you employ, it can be broken if someone cares enough. Wire communications can be tapped too, of course, but you're much more likely to know that someone's attached a device to your patch cable...and they had to get past your physical security as well.
Wireless won't be reliably securable (even in the limited "my data aren't worth the trouble it would take to get them" sense) until quantum encryption becomes commonplace: at least you'll know if someone's intercepting your data.
Although, come to think of it, one could probably design a one-time-pad system that would work conveniently enough. You've got two devices that need to talk to each other...give one of them the ability to generate a random keystream x million characters long...set it up such that it can share the keystream with the other device, but only over a hard connection...synch it up once, and then consume the keystream character by character as the two devices communicate. Generate new noise whenever you run out of keystream, and resynch your communications.
Now that it's occurred to me, it seems so obvious I have to think someone's already done it.
Of course, if not, can I have the patent on the class of devices described in this post?
