ABSTRACT:
Trusted entity authentication includes creating a public-private pair in a secure environment; storing the private key within a device during its manufacture in the secure environment; linking the public key with other information in the secure environment, receiving input within the device comprising verification data of an entity, identifying within the device a verification status based on the verification data and data prestored within the device; independent of the verification status identified, generating a digital signature for a message including an indication of the identified verification status using the private key; outputting the digital signature for transmission with an EC; identifying upon receipt of the EC the information linked with the public key by authenticating the message with the public key, and considering the identified information and the indicated verification status. The linked information includes device security aspects and the verification status regards entity authentication performed by the device.
