Abstract
Embodiments described herein enable multi-user storage volume encryption via a secure enclave processor. One embodiment provides for a computing device comprising a first processor to execute a first operating system having one or more user accounts; a second processor to execute a second operating system, the second processor including a secure enclave, the secure enclave to receive a first encrypted key from the first processor and decrypt a volume encryption key via a key encryption key derived from the first encrypted key, the first encrypted key derived via the secure enclave without user-provided entropy; and a non-volatile memory controller to access encrypted data within non-volatile memory using the volume encryption key.
