Apple needed a crypto-security win after the SSL fiasco. It’s good to see that, at least in theory, this approach to securing iMessage is smart and honestly secure.

Maybe a handful. Up until now, the vast majority of what we knew about iMessage’s inner workings came from reverse engineering and best guesses. This week, however, Apple quietly released a document that breaks it all down.
If you know your stuff when it comes to cryptography, you can find the document here. The iMessage bit starts at page 20, but there’s all sorts of crazy interesting stuff regarding cloud keychain and hardware security packed in there too.
