Abstract
Systems and method for producing, validating, and registering authentic verification tokens are disclosed. Such systems and methods include generating verification token specific key pairs. The key pairs can be signed by a verification token manufacturer master key or public key certificate for an additional level of authenticity. Related methods and systems for authenticating and registering authorized verification token manufacturers are also disclosed. Once a verification token manufacturer is authenticated, it can be assigned a manufacturer-specific key pair or certificate and in some cases, a predetermined set of serial numbers to assign to the verification tokens it produces. Each serial number can be used to generate a verification token specific key pair specific to the associated verification token. One component of the verification token key pair can be stored to the verification token. Optionally, the component of the verification token key pair stored to the verification token can be signed by the manufacturer specific master key or certificate and stored a verification token public certificate.
