An updated Apple security document on the company’s “iPhone in Business” site provides more information on security details regarding the iPhone’s Touch ID feature and A7 chip. The document describes the A7 chip’s Secure Enclave coprocessor, which uses encrypted memory and a hardware random number generator to securely store user credentials and communicate with the Touch ID sensors. “Each Secure Enclave is provisioned during fabrication with its own UID (Unique ID) that is not accessible to other parts of the system and is not known to Apple,” the document notes. The Secure Enclave processes fingerprint data from the Touch ID, which is encrypted in the Touch ID sensor and authenticated with the Secure Enclave using a device-specific key. Apple has also updated the document to include more info about security in other areas, such as iCloud Keychain, AirDrop, iMessage, and FaceTime. [via TechCrunch]
