Abstract
Securing the manufacturing supply chain with digital certificates. A token is coupled to a manufacturing station and enabled via a personal identification number. The token includes a counter limiting the maximum number of certificates to be signed, and compares a serial number of a digital certificate to a tracked serial number. In some embodiments, the token is linked to a particular manufacturing station once the token is enabled.
