Systems and methods for securing the manufacturing supply chain

A method for signing digital certificates, the method comprising:

• cryptographically coupling a token to a manufacturing station, wherein the token includes a counter representing a number of signed digital certificates and a maximum value for the counter;
• enabling the token based on a personal identification number received by the manufacturing station;
• determining that a value stored in the counter is less than the maximum value;
• in response to determining that the value stored in the counter is less than the maximum value;
• obtaining a public key from an electronic device,
• binding the public key to a digital certificate that is currently unsigned,
• determining that a serial number associated with the digital certificate matches a serial number associated with a serial number tracker in the token, and
• in response to determining that the serial number associated with the digital certificate matches the serial number associated with the serial number tracker in the token,
• signing the digital certificate with the public key;
• modifying the serial number in the serial number tracker to the next serial number expected;
• incrementing the counter following the signing of the digital certificate;
• and
• returning the signed digital certificate to the electronic device.
