Abstract

In the field of computer and data security, the identifier (ID) of a computing device is protected by providing a secure signature used to verify the ID. The signature is computed from the ID using a “White Box” cryptographic process and a hash function. This provides a signature that is computationally easy to verify but difficult or impossible to generate by a hacker (unauthorized user). This method of first creating the signature and later verifying the identifier using the signature and the associated computing apparatus are thereby useful for protection against hacking of such identifiers of computing devices.
