How Apple Protects Your iCloud Keychain

Apple recently released a new version of its iOS Security white paper, which gives an overview and some details of the security systems built into iOS. Over at TidBITS, Rich Mogull’s title was How to Protect Your iCloud Keychain from the NSA. It really should have been, “How Apple Protects Your iCloud Keychain”, but that wouldn’t get as much attention. Clickbait title aside, he does a good job of summarizing some of the implementation details, and explaining exactly how extensive the protections are for at least this aspect of iOS.
