Abstract
Systems and methods are disclosed herein for protecting data in a storage device by encrypting or decrypting the data with a Data Encryption Key (DEK). The storage device is communicatively coupled to a host. In one example, the storage device comprises at least one Physically Unclonable Function (PDF) configured to generate PDF responses based on challenges and an authentication output generation module configured to obtain a nonce from the host, obtain an input related to a first PDF response, generate an authentication output based on the input and the nonce using a One-Way Function (OWF), and provide the authentication output to the host. The storage device further comprises a DEK generation module configured to generate a DEK based on a second PDF response and a crypto module to perform encryption or decryption of data using the DEK.
