How Apple’s unmatched A7 64-bit processor gives iOS plenty of headroom for the future and Apple a distinct competitive advantage: Bisson writes, “With a virtualisation-ready processor in its new phone, Apple can now start to move iOS in the direction of a hypervisor-controlled sandbox environment… Here the operating system component of a VM is tailored to the application it is hosting – minimising the attack surface of each secure partition. Combined with a fingerprint sensor to identify users, Apple has the tools it needs to deliver biometric access control, allowing devices to support multiple users, with files and apps for one user hidden from another using hardware encryption.”
