Systems and methods to secure personally identifiable information

A device comprising:

• a memory array;
• control logic communicatively coupled to the memory array;
• a one-time programmable (OTP) memory bank, the OTP storing at least one key;
• and
• authentication logic the authentication logic configured to:
• transmit an encrypted command to a processing device, the encrypted command comprising a proof-of-work requirement,
• receive a response from the processing device, the response including an encrypted result of executing the encrypted command, and
• decrypt the response to obtain a decrypted result.

A non-transitory computer readable storage medium for tangibly storing computer program instructions capable of being executed by a processor, the computer program instructions defining steps of:

• transmitting an encrypted command to a processing device, the encrypted command comprising a proof-of-work requirement;
• receiving a response from the processing device, the response including an encrypted result of executing the encrypted command;
• decrypting the response to obtain a decrypted result;
• and
• detecting that the decrypting failed if the decrypted result is not equal to an expected result of the encrypted command.
