Abstract
Methods, devices, and systems of protecting a secret are provided. Access to the secret is designed to be restricted to a code with a specific signature, or fingerprint. The signature of that code is used in the encryption of the secret, and other codes are prevented from using this signature to decrypt the secret. This restricted access to the secret prevents the secret from being easily compromised, for example, by preventing a change in the code.
