Abstract
A method for a device comprises enrolling a specified application installed on the device into a chain of trust provided by a private key infrastructure. In the chain of trust, a child certificate is attested as valid by an attestor associated with a parent certificate in the chain of trust. Enrolling includes generating an application certificate-A for verifying that the specified application is installed on the device. The application certificate is a descendant certificate of the device certificate associated with the device and the chain of trust.
