Yeesh. Marked as spam? There’s a lot in this paper. Even if you don’t use an iPhone, it’s good reading. You might learn something.
It’s quite a fantastic read. There’s nothing really innovative, but it really does go to show that security was pretty thoroughly thought about at Apple. I was extremely skeptical on how iMessages handles end to end encrypted messages when a new device is added to the trusted device pool and read the paper about how they use crypto in iMessages. They got all their bases pretty much covered.
