Abstract

Techniques for reconstructing a die unique wrapping key from non-volatile (NVM) memory by a memory controller circuit are described. In certain examples, a computer system includes a processing circuit to perform one or more operations according to the one or more values; a non-volatile memory; and a memory controller circuit coupled to the non-volatile memory, the memory controller circuit to: read data from the non-volatile memory, read a key mask from the non-volatile memory, perform a hashing operation on the data from the non-volatile memory to generate a digest value, perform a reversible function on the digest value and the key mask to recover a wrapping-key, and decrypt encrypted data of the data with the wrapping-key to recover one or more values for the processing circuit.
