Abstract
Disclosed is a storage device which includes a nonvolatile memory device that stores booting data and user data, and a memory controller that includes a first core, a second core, and third cores. In an initialization operation, the first core performs first authentication on at least a first part of the booting data. In response to that the first authentication succeeds, the first core generates a device identifier, and the second core loads the first part of the booting data and performs first booting. The first core performs second authentication on at least a second part of the booting data. In response to that the second authentication succeeds, the first core generates a first certificate and a second certificate, and the second core loads the second part of the booting data and performs second booting.
