Abstract
An apparatus comprises a circuit for generating a secret root key having bits representative of threshold voltages, and an error correction module for correcting errors in bits of the secret root key to produce a corrected secret root key. A method of generating a secret root key and a data storage system that includes a secret root key are also described.
Claims20
An electronic device comprising:
- a circuit for generating a secret root key having bits representative of threshold voltages;
- and
- an error correction module for correcting errors in bits of the secret root key to produce a corrected secret root key.
A method of producing a secret root key for an electronic device, the method comprising:
- producing a plurality of logic ones and zeros in response to threshold voltages;
- and
- error correcting the plurality of logic ones and zeros to produce a corrected secret root key.
A data storage system comprising:
- a storage medium;
- a controller including a cryptographic and security module for encrypting and decrypting data to be stored in and retrieved from the storage medium, wherein the cryptographic and security module includes:
- a circuit for producing a secret root key having bits representative of threshold voltages;
- and
- an error correction module for correcting errors in bits of the secret root key.
