Abstract: A method of encrypting unencrypted digital content includes measuring an analog value associated with a physical property of interested cells of a memory array; digitizing the measured analog value to generate a response key; generating an encryption key based at least on the response key; encrypting the unencrypted digital content to generated encrypted digital content based on the encryption key; and storing the encrypted digital content.

Abstract: A method generating a cryptographic key and corresponding helper data includes measuring an analog value associated with a physical property of cells of a memory array; digitizing the measured analog value to generate the cryptographic key; quantizing the measured analog value to generate the corresponding non-leaky helper data.
