The talk by Andrey Belenko from PasswordsCon Bergen 2013 focuses on protection of user data. It reviews iOS Data Protection and changes that iOS 7 brought to it. The author explores in great detail the inner workings of the new iCloud service — 'escrowproxy' — which is the essence of the iCloud Keychain. Other iCloud services, such as iCloud Backup, receive some attention, too.
The main giveaway of the talk is the in-depth analysis of the new iCloud Keychain feature. You learn how, when, and where things are encrypted, and what it takes to decrypt them.
