FYI: Apple iOS security white-paper

[Jens Alfke]

A few days ago Apple released a white paper [PDF link] describing the security features of iOS. It’s a must-read if you’re interested in keeping app data secure, or just curious how the security features work. It goes into quite a lot of detail about the hardware encryption support, the algorithms used to encrypt files, the exact meanings of the different file-protection modes, and so on.
