The method includes obtaining a first private key for use with a first operation of the printing device and obtaining a second private key for use with a second operation of the printing device. The method also includes loading the first private key into a secure memory portion of the printing device during manufacturing of the printing device, and loading the second private key into the secure memory portion of the printing device during manufacturing of the printing device.
Claims17
A printing device comprising:
- a housing;
- a card input in the housing;
- a card travel path that extends through the housing from the card input;
- a print engine disposed along the card travel path;
- a non-secure memory portion;
- and
- a secure memory portion that is an isolated memory portion and is distinct and/or separate from the non-secure memory portion, wherein the secure memory portion includes a crypto processor, wherein the secure memory portion stores a unique and secure identity of the printing device,
- wherein the secure memory portion has access to at least one private key, each of the at least one private key associated with an operation performed by the printing device,
- wherein the crypto processor validates an authorization request associated with a requested operation to be performed by the printing device using the at least one private key associated with the requested operation, and
- wherein the printing device performs the requested operation upon validation by the crypto processor of the authorization request,
- wherein the printing device stores at least one public key or cryptographic hash associated with a secure boot operation.
