Abstract
A computing device includes a non-volatile memory (NVM) interface and a processor. The NVM interface is configured to communicate with an NVM. The processor is configured to store in the NVM at least (i) data entries including data and (ii) mapping entries including mapping information that indicate physical addresses in which the data entries are stored in the NVM, and to verify authenticity of the data entries and of the mapping entries using a hierarchical authentication scheme in which (i) the data entries include first authentication information that authenticates the data, and (ii) the mapping entries include second authentication information that authenticates both the mapping information and the data entries.
