Abstract
Technology that provides security for a requestor of data stored in a non-volatile memory device is disclosed. In one aspect, the non-volatile memory device provides data on a host interface only if a digest for the data matches an expected digest for the data. The non-volatile memory device may store expected digests for data for various logical addresses. Upon receiving a request on the host interface to read data for a logical address, the non-volatile memory device may access the data for the logical address, compute a digest for the accessed data, and compare the computed digest with the expected digest. The non-volatile memory device provides the accessed data on the host interface only if the computed digest matches the expected digest, in one aspect. The non-volatile memory device may be used to provide a secure boot of a host.
