As reported by The Register, Apple released iOS 10.3 today. Included in the update is a new file system designed specifically for iOS devices. The Apple File System (APFS) is designed for macOS, iOS, tvOS, and watchOS.
APFS brings strong “full-disk encryption” to protect files and metadata from exposure. The interesting part is that APFS uses a multi-key encryption. One key protects the data and a separate key protects metadata. Separating these keys makes the attacker’s job more difficult.
Last year there was a very public debate around the role of encryption and backdoors for law enforcement investigations. Apple fought FBI requests to decrypt an iPhone used by terrorists in California. The FBI eventually found a way to decrypt the phone without Apple’s aid.
Doubling down on encryption, Apple is now making the process to gain access to iOS devices even more difficult. It seems that relevant XKCD is even more relevant for Apple devices.
